import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class SwingDemo {

JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
panel.setLayout(new GridBagLayout());
GridBagConstraints constraints = new GridBagConstraints();
constraints.gridx = 0;
panel.add(new JButton("1st row"), constraints);
constraints.gridx = 1;
constraints.gridy = GridBagConstraints.RELATIVE;
panel.add(new JButton("1st row 2nd column"), constraints);
panel.add(new JButton("2nd row 2nd column"), constraints);
frame.add(panel);
frame.setSize(550, 300);
