Reconstructing Java Code

since I am advancing with the help of my little program, I have a button 4, which are rules by the same rules, and I don’t know how to reduce the code, I’m almost sure that this can be simplified:

private void initGame(Quizz quizz) {

    jLabelScore = new javax.swing.JLabel();
    jLabelComptQ = new javax.swing.JLabel();
    jButtonA = new javax.swing.JButton();
    jButtonB = new javax.swing.JButton();
    jButtonC = new javax.swing.JButton();
    jButtonD = new javax.swing.JButton();

    int i = quizz.aleatQuestion();
    ArrayList<Reponse> listeRep = quizz.showAnswer(i);
    Reponse reponseA = listeRep.get(0);
    Reponse reponseB = listeRep.get(1);
    Reponse reponseC = listeRep.get(2);
    Reponse reponseD = listeRep.get(3);

    jButtonA.setText(reponseA.getReponse());
    jButtonB.setText(reponseB.getReponse());
    jButtonC.setText(reponseC.getReponse());
    jButtonD.setText(reponseD.getReponse());
    jLabelScore.setText("Score : " + quizz.getScore());
    int a = quizz.getCompteurQ()+1;
    jLabelComptQ.setText("Question n°" + a);

    setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
    setTitle("Jeu en Cours - StudenTest");
    setCursor(new java.awt.Cursor(java.awt.Cursor.DEFAULT_CURSOR));
    setMaximumSize(new java.awt.Dimension(800, 600));
    setMinimumSize(new java.awt.Dimension(800, 600));
    setResizable(false);
    setSize(new java.awt.Dimension(800, 600));
    getContentPane().setLayout(null);
    getContentPane().removeAll();

    getContentPane().add(jLabelScore);
    jLabelScore.setBounds(0, 20, 250, 250);
    jLabelScore.setVerticalAlignment(SwingConstants.TOP);

    getContentPane().add(jLabelComptQ);
    jLabelComptQ.setBounds(0, 0, 250, 250);
    jLabelComptQ.setVerticalAlignment(SwingConstants.TOP);

    jButtonA.addMouseListener(new java.awt.event.MouseAdapter() {
        @Override
        public void mouseClicked(java.awt.event.MouseEvent evt) {
            if (reponseA.getVerif()) {
                quizz.win();
            } else {
                quizz.lose();
            }
            quizz.endOfTurn();
            if (quizz.getCompteurQ() >= 5) {
                Component frame = null;
                JOptionPane.showMessageDialog(frame, "Score Final :" + quizz.getScore() + "\nBien Joué");
                initComponents();
            } else {
                initGame(quizz);
            }
        }

    });
    getContentPane().add(jButtonA);
    jButtonA.setBounds(425, 325, 150, 75);

    jButtonB.addMouseListener(new java.awt.event.MouseAdapter() {
        @Override
        public void mouseClicked(java.awt.event.MouseEvent evt) {
            if (reponseB.getVerif()) {
                quizz.win();
            } else {
                quizz.lose();
            }
            quizz.endOfTurn();
            if (quizz.getCompteurQ() >= 5) {
                Component frame = null;
                JOptionPane.showMessageDialog(frame, "Score Final :" + quizz.getScore() + "\nBien Joué");
                initComponents();
            } else {
                initGame(quizz);
            }
        }
    });
    getContentPane().add(jButtonB);
    jButtonB.setBounds(225, 325, 150, 75);

    jButtonC.addMouseListener(new java.awt.event.MouseAdapter() {
        @Override
        public void mouseClicked(java.awt.event.MouseEvent evt) {
            if (reponseC.getVerif()) {
                quizz.win();
            } else {
                quizz.lose();
            }
            quizz.endOfTurn();
            if (quizz.getCompteurQ() >= 5) {
                Component frame = null;
                JOptionPane.showMessageDialog(frame, "Score Final :" + quizz.getScore() + "\nBien Joué");
                initComponents();
            } else {
                initGame(quizz);
            }
        }
    });
    getContentPane().add(jButtonC);
    jButtonC.setBounds(425, 450, 150, 75);

    jButtonD.addMouseListener(new java.awt.event.MouseAdapter() {
        @Override
        public void mouseClicked(java.awt.event.MouseEvent evt) {
            if (reponseD.getVerif()) {
                quizz.win();
            } else {
                quizz.lose();
            }
            quizz.endOfTurn();
            if (quizz.getCompteurQ() >= 5) {
                Component frame = null;
                JOptionPane.showMessageDialog(frame, "Score Final :" + quizz.getScore() + "\nBien Joué");
                initComponents();
            } else {
                initGame(quizz);
            }
        }
    });
    getContentPane().add(jButtonD);
    jButtonD.setBounds(225, 450, 150, 75);

    pack();

    setLocationRelativeTo(null);
}

You can see that reponseA / B / C / D and jButtonA / B / C / D follow the same instructions. I looked at the lesson I had, but I did not find any help for this problem, even if it helped me a lot. I tried to do an online study, but it was not connected or the solution did not fit ... I hope you understand what I said (I do not speak English).

Ps: I allowed all the method code, but if necessary, I can remove the part that is not completely necessary.
