      JFrame frame = new JFrame("Swing Tester");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      createUI(frame);
      frame.setSize(560, 200);      
      frame.setLocationRelativeTo(null);  
      frame.setVisible(true);

      panel.add(label);
      panel.add(textField);

      layout.putConstraint(SpringLayout.WEST, label,5, SpringLayout.WEST, panel);
      layout.putConstraint(SpringLayout.NORTH, label,5, SpringLayout.NORTH, panel);
      layout.putConstraint(SpringLayout.WEST, textField,5, SpringLayout.EAST, label);
      layout.putConstraint(SpringLayout.NORTH, textField,5, SpringLayout.NORTH, panel);
      layout.putConstraint(SpringLayout.EAST, panel,5, SpringLayout.EAST, textField);
      layout.putConstraint(SpringLayout.SOUTH, panel,5, SpringLayout.SOUTH, textField);
