Add properties, with getter/setter methods,
to the dialog object.  Very straightforward.

   public class MyDialog extends JDialog {
     ...
     private boolean wasCanceled = true;

     // I omit member fields, constructor
     // for the sake of brevity ...

     public String getUserName() {
       return userNameTF.getText();
     }
     public void setUserName(String name) {
       userNameTF.setText(name);
     }
     // Do the same for the password.
     ...
     // Also, keep a record of which button the
     // user pressed.  Add actionListeners to the
     // OK and Cancel buttons and set the "wasCanceled"
     // field.

     public boolean wasCanceled() { return wasCanceled; }
   }


When calling your dialog:

   MyDialog d = new MyDialog(...);
   d.setModal(true);
   d.setUserName("Roel");
   d.show();
   if ( ! d.wasCanceled() ) {
     String uname = d.getUserName();
     String pw = d.getPassword();
     // do what you have to do with
     // this info ...
   }
   d.dispose();

Yes, but there is a big difference between "cannot" and "should not".  

In Paul's code, the purpose of the wasCanceled() method is to indicate
whether the dialog was canceled.  If you have that code dispose of the
dialog, that is not doing what most people would expect the method to
do.  The example code Paul gave that calls the dialog would work, but
if someone wrote some slightly different code, it might not.
