How to use GroupLayout to set it component on right side?

Question

is there anyway to move the b_ok and b_cancel to right side instead of left side?
thanks~
import javax.swing.*;
public class Test extends JPanel
{   public static void main(String[] args)
    {     SwingUtilities.invokeLater(new Runnable() {
            public void run()
         {     new Test();
    JFrame frame;
    Test()
    {     System.out.println("Created GUI on EDT? " + SwingUtilities.isEventDispatchThread());
     frame = new JFrame();
        frame.setContentPane(createGUI());
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    private JPanel createGUI()
    {     JPanel p = new JPanel();
         GroupLayout layout = new GroupLayout(p);
            layout.setAutoCreateGaps(true);
            layout.setAutoCreateContainerGaps(true);
         p.setLayout(layout);
         JLabel l = new JLabel("Test");
         JTextArea txtA = new JTextArea(3,25);
         JButton b_ok = new JButton("OK");
         JButton b_cancel = new JButton("Cancel");
          layout.setHorizontalGroup(layout.createSequentialGroup()
                .addGroup(layout.createParallelGroup()
                    .addComponent(l)
                    .addComponent(txtA)
               .addGroup(layout.createSequentialGroup()
                        .addComponent(b_ok)
               .addComponent(b_cancel))
          layout.setVerticalGroup(layout.createSequentialGroup()
                .addComponent(l)
           .addComponent(txtA)
               .addGroup(layout.createParallelGroup()
                            .addComponent(b_ok)
                            .addComponent(b_cancel))
         return p;
}

This also moves the lable to the right, so you may move the Buttons to an outer JPanel, lable and text area to an inner Panel...layout.setHorizontalGroup(layout.createSequentialGroup().addGroup(
  layout.createParallelGroup(Alignment.TRAILING) // this does the trick
    .addComponent(l).addComponent(txtA).addGroup(
       layout.createSequentialGroup().addComponent(b_ok).addComponent(b_cancel))));bye
