    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    contentPane.setLayout(groupLayout);// ww  w  .ja  va  2 s  . com

    JButton b1 = new JButton("Button 1");
    JButton b2 = new JButton("this is a test 2");

    groupLayout.setHorizontalGroup(groupLayout.createSequentialGroup()
        .addComponent(b1).addComponent(b2));

    groupLayout.setVerticalGroup(groupLayout
        .createParallelGroup(GroupLayout.Alignment.BASELINE).addComponent(b1)
        .addComponent(b2));
