    JLabel label = new JLabel("java2s.com");

    JFrame frame = new JFrame("Testing");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setLayout(new BorderLayout());
    frame.add(label);

    JPanel buttons = new JPanel(new GridLayout(0, 1));
    for (int index = 0; index < 10; index++) {
      buttons.add(new JButton(String.valueOf(index)));
