Instead of using BorderLayout to place both the slider and the label, create a panel containing both components, then use BorderLayout to place the panel.

Replace

this.add(slider, BorderLayout.PAGE_END);
this.add(sliderLabel, BorderLayout.LINE_END);

With

JPanel sliderPanel = new JPanel();
sliderPanel.setLayout( new FlowLayout(FlowLayout.TRAILING));
sliderPanel.add(slider);
sliderPanel.add(sliderLabel);
this.add(sliderPanel, BorderLayout.PAGE_END);

This is based on code I used to place an OK and Cancel button at the bottom of a dialog. This might not compile - but you get the idea. Play around with the arguments to FlowLayout and change the order of adding to the slider panel until you get the look you want.

BTW - since you are doing the layout yourself - not using a GUI builder - you might as well get rid of the initComponents method and the surrounding comments. I'm guessing that you are using Netbeans and created a panel that was initially configured to use GroupLayout, and Netbeans injected that code. Now it's just getting in the way.
