New to Java

Hi all, first post here, I need some help with a high school Java project which is throwing a stack overflow exception everytime I click a button which runs a method. It's basically a database program for storing information of computer game characters. It's a very simple problem compared to the complexity of a lot of the other problems I have read about here - it grabs info I have in a form on a GUI, then tries to add it to a binary tree then save it to a file.

I'm tearing my hair out with this project, I'd be really appreciative of anybody who would be willing to help me out, if so please drop me an email at g0t-h4x@optusnet.com.au or just leave your email here. I want to be able to talk through the problem and understand why it won't work, because I've done some reasearch and judging by example codes I've been given, there's nothing wrong. I hope this doesn't sound like I'm begging or whining or pleading for someone to make my whole project, but I just want to be able to go through the Overflow error and understand why it's happening.

Thanks.
