Using two graphical interfaces from one source

Question

I am working on an existing project and want to simplify and use it. I have two GUIs that I want them to feed on only one resource, as well as some GUI codes. I mean, that gui1.javathey gui2.javaconsist of their GUI codes. And one for their common parts. Let me call him common.java. With the gui selection part, I can satisfy the selected gui (gui1 or gui2). I think to expand common.javaon JFrame, then continue gui1.javaand gui2.javawith help common.java. Moreover, if there is an external part of one of these graphical interfaces, I can add the external part using the if condition (as I said, I can determine which gui is selected.) For example:

protected void MovementStateControl() {
        try {
            URL url = new URL(NameofMyproject.GetWepIp() + "<MESSAGE><Command_No>4</Command_No></MESSAGE>");
            URLConnection connection = url.openConnection();
            Document doc = parseXML(connection.getInputStream());
            NodeList Settings = doc.getElementsByTagName("SYSTEM_SETTINGS");
            Node MovementSystem = Settings.item(0);
            Element MovementElem = (Element) MovementSystem;
            jLabel7.setText(MovementElem.getElementsByTagName("device_name").item(0).getTextContent());
            SystemGuiSelect.DeviceName = MovementElem.getElementsByTagName("device_name").item(0).getTextContent();
            NameofMyproject.signal_max_level = Integer.parseInt(MovementElem.getElementsByTagName("signal_max_val").item(0).getTextContent());

            /* If gui1 is selected, the part should be done as well. Otherwise, just above part okay. */
            if (gui1) {
                NameofMyproject.signal_min_level = Integer.parseInt(MovementElem.getElementsByTagName("signal_min_val").item(0).getTextContent());
                if (!"EXISTS".equals(MovementElem.getElementsByTagName("polarization_system").item(0).getTextContent())) {
                    jLabel24.setVisible(false);
                    LblPolAngle.setVisible(false);
                    lblPolTarget.setVisible(false);
                    jLabel13.setVisible(false);
                    jTextField3.setVisible(false);
                    jButton16.setVisible(false);
                    jButton8.setText("Tx-Xy");
                    jButton3.setVisible(false);
                    jButton4.setVisible(false);
                    jProgressBar3.setVisible(false);
                    jLabel36.setVisible(false);
                    jLabel37.setVisible(false);
                    jLabel5.setVisible(false);
                    jButton18.setVisible(false);
                } else {
                    jLabel24.setVisible(true);
                    LblPolAngle.setVisible(true);
                    lblPolTarget.setVisible(true);
                    jLabel13.setVisible(true);
                    jTextField3.setVisible(true);
                    jButton16.setVisible(true);
                    jButton8.setText("Tx-Xy-Zu");
                    jButton3.setVisible(true);
                    jButton4.setVisible(true);
                    jProgressBar3.setVisible(true);
                    jLabel36.setVisible(true);
                    jLabel37.setVisible(true);
                    jLabel5.setVisible(true);
                    jButton18.setVisible(true);
                }
            }

        } catch (Exception e) {  }
    }

You common.java should consist of specialized containers. This will separate common.java from gui1.java and gui2.java, in the future, if you need to add a new gui3.java, you will not break any APIs and just create a new SpecializedGUI.java
