Button b1 = new Button("one");
GridBagConstraints c1 = new GridBagConstraints();
c1.gridx = 0;
c1.gridy = 0;
c1.gridwidth = 1;
c1.gridheight = 1;
c1.fill = GridBagConstraints.BOTH;
c1.anchor = GridBagConstraints.CENTER;
frame.add(b1, c1);
         
Button b2 = new Button("two");
GridBagConstraints c2 = new GridBagConstraints();
c2.gridx = 1;
c2.gridy = 0;
c2.gridwidth = 1;
c2.gridheight = 1;
c2.fill = GridBagConstraints.BOTH;
c2.anchor = GridBagConstraints.CENTER;
frame.add(b2, c2);
                 
Button b3 = new Button("three");
GridBagConstraints c3 = new GridBagConstraints();
c3.gridx = 0;
c3.gridy = 1;
c3.gridwidth = 2;
c3.gridheight = 1;
c3.fill = GridBagConstraints.BOTH;
c3.anchor = GridBagConstraints.CENTER;
frame.add(b3, c3);
