    content.setLayout(layout);

    JButton[] buttons = new JButton[6];
    SpringLayout.Constraints constr = null;
    for (int i = 0; i < buttons.length; i++) {
        buttons[i] = new JButton("Press " + (i + 1));
        content.add(buttons[i]);
    }

    Spring xSpring = Spring.constant(5, 15, 25);
    Spring ySpring = Spring.constant(10, 30, 50);

    constr = layout.getConstraints(buttons[0]);
    constr.setX(xSpring);
    constr.setY(ySpring);

    for (int i = 1; i < buttons.length; i++) {
        constr = layout.getConstraints(buttons[i]);
        layout.putConstraint(SpringLayout.WEST, buttons[i], xSpring, SpringLayout.EAST, buttons[i - 1]);
        layout.putConstraint(SpringLayout.NORTH, buttons[i], ySpring, SpringLayout.SOUTH, buttons[i - 1]);
    }
    aWindow.setVisible(true); // Display the window
