    Component left = new JLabel("Left");

    layout.putConstraint(SpringLayout.WEST, left, 10, SpringLayout.WEST, contentPane);
    layout.putConstraint(SpringLayout.NORTH, left, 25, SpringLayout.NORTH, contentPane);
    layout.putConstraint(SpringLayout.NORTH, right, 25, SpringLayout.NORTH, contentPane);
