JButton jb8 = new JButton("H");
JButton jb9 = new JButton("I");
JButton jb10 = new JButton("J");
JButton jb11 = new JButton("K");
JButton jb12 = new JButton("L");
JPanel jp1 = new JPanel( );
jp1.add(jb1);
jp1.add(jb2);
jp1.add(jb3);
jp1.add(jb4);
JPanel jp2 = new JPanel(new GridLayout(4, 1));
jp2.add(jb5);
jp2.add(jb6);
jp2.add(jb7);
jp2.add(jb8);
JPanel jp3 = new JPanel(new GridLayout(2, 2));
jp3.add(jb9);
jp3.add(jb10);
jp3.add(jb11);
jp3.add(jb12);
JPanel jp4 = new JPanel(new BorderLayout( ));
jp4.add(jp1, BorderLayout.NORTH);
jp4.add(jp2, BorderLayout.EAST);
jp4.add(jp3, BorderLayout.WEST);
JFrame jf = new JFrame( );
jf.getContentPane( ).add(jp4);
jf.pack( );
jf.setVisible(True);
