import java.awt.GridBagLayout;

import javax.swing.JButton;

public class Main {
  public static void main(String[] argv) throws Exception {
    JFrame frame = new JFrame();

    frame.setLayout(gbl);
    frame.add(new JButton("1"));
    frame.add(new JButton("2"));

    gbl.layoutContainer(frame);


    gbl.columnWeights = new double[]{0.0f, 1.0f, 2.0f};
