Ok, here's a problem. I have trouble figuring out GroupLayout. I was able to add two JTextFields and two JLabels but when I tried to add some JButtons and stuff, it started throwing IlegalStateExceptions. So I just merely told it to add but it still won't show up.
Also, I added the components that I'd like to add, though I may come up with more later, but anyway, I put them into a JPanel and showed them with a JFrame. I can't even get the layout of this new JPanel to show three buttons on one level and one checkbox below it. All I get at best is a 2 by 2.

The problem is in the TextBasedDocumentMenu class, I only included the other two to make it compile and fully run without having to delete code.
