BorderLayout implemented in terms of GroupLayout

Just for fun. Here is a java.awt.BorderLayout implemented in terms of javax.swing.GroupLayout:

import javax.swing.GroupLayout;
import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class BorderLayoutGroupLayout {
    public static void main(String[] args) {
        JButton west = new JButton("West");
        JButton north = new JButton("North");
        JButton east = new JButton("East");
        JButton south = new JButton("South");
        JButton center = new JButton("Center");
       
        JPanel panel = new JPanel();
        GroupLayout groupLayout = new GroupLayout(panel);
        panel.setLayout(groupLayout);
       
        groupLayout.setHorizontalGroup(
            groupLayout.createParallelGroup(GroupLayout.Alignment.LEADING)
                .addComponent(north, GroupLayout.PREFERRED_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)
                .addGroup(groupLayout.createSequentialGroup()
                    .addComponent(west)
                    .addComponent(center, GroupLayout.PREFERRED_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)
                    .addComponent(east))
                .addComponent(south, GroupLayout.PREFERRED_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)
        );
        groupLayout.setVerticalGroup(
            groupLayout.createSequentialGroup()
                .addComponent(north)
                .addGroup(groupLayout.createParallelGroup(GroupLayout.Alignment.CENTER)
                    .addComponent(west, GroupLayout.PREFERRED_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)
                    .addComponent(center, GroupLayout.PREFERRED_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)
                    .addComponent(east, GroupLayout.PREFERRED_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE))
                .addComponent(south)               
        );
        JDialog dialog = new JDialog((JFrame)null, "", true);
        dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
        dialog.setContentPane(panel);
        dialog.pack();
        dialog.setVisible(true);
    }
}
