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();
