I need to add a border around the Size label and the small, medium and large buttons so I thought I would add them into their own Panel and then add that panel to the mainPanel but when I do that they do not show up.

What am I doing wrong? :-/ Thanks guys!

my view, very very bad,

is posible to put Image directly to JPanel, withOut method paintComponent (this Method works for JPanel, for Panel is correct paint )

please search for JPanel instead of Panel

sizes.setBorder(new LineBorder(Color.black, 1));

you have to start with http://download.oracle.com/javase/tutorial/uiswing/

and be sure that you'll read http://download.oracle.com/javase/tutorial/uiswing/layout/index.html

lots of examples for that on http://www.java2s.com/

if you'll a real question feel free to send it here

You set your frame layout to null, but never set the location of your panel. The following will make them show up within the panel (though it's not a layout you're going to want to keep once you see it)

JPanel p=new JPanel();
p.setLayout(new FlowLayout());
p.setBounds(20,20,100,130);
p.add(sizes);
p.add(small);
p.add(med);
p.add(large);

I'd recommend going though some of the layout tutorial linked above. Absolute positioning with null layout is usually not the best way to approach a design.
