import javax.swing.JDialog;
import javax.swing.JFrame;
public class SwingDemo {
   public static void main(String[] args) {
      JFrame frame = new JFrame();
      frame.setSize(new Dimension(600, 400));
      JDialog dialog = new JDialog(frame, "New",ModalityType.MODELESS);
      dialog.setSize(300, 300);
      frame.add(new JButton(new AbstractAction("Click to generate") {
         @Override
         public void actionPerformed(ActionEvent e) {
            frame.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
            dialog.setVisible(true);
         }
      }));
      frame.setVisible(true);
   }
