Answer 1

Sort of

var textBox = new TextBox();
textBox.TextMode = TextBoxMode.MultiLine;

You will also have to record rendering in order to be sensitive to what mode you are in:

if( (WebPartManager.DisplayMode == WebPartManager.DesignDisplayMode) || 
    (WebPartManager.DisplayMode == WebPartManager.EditDisplayMode) ) {
       //Show your textbox
} else {
       //Render as text
}
