There are two standard printed references on Swing. Both are in the range of 900 pages long and explain Swing quite thoroughly. If you can't get ahold of one of those, there are many on-line tutorials (including ones released by Sun and those made by third-party writers). Sun's on-line documentation of the Swing classes is really quite good.
If you're not going to even TRY to come up with an answer, how can you expect anyone to want to help you out?

Um... you're not tracking me very well, are you? Yes, you'd want to change a lot of stuff, depending on what Swing capabilities you wanted to make use of. But unless you try to understand what Swing does, and how it sits on top of the AWT (which I don't fully understand yet, myself) all you're doing is asking people to write code for you for free. Most of us have plenty of stuff to write, we're here to help you understand, not to do your work for you.
