Thread: Connect Four GUI

Hey guys, first post here asking for help with some grade 11 compsci work. We're required to make a connect four: no AI, 2 players, nothing fancy like reset buttons etc. just buttons that change colour and can detect when a player wins. I'm having a lot of trouble with this, could you take a few minutes to look it over and tell me what's wrong, if there's anything at all I did right, and what I should do to make it work? Right now, I suspect that I'm not allowed to make new jbuttons inside a for loop, but if not how should I do it? Thanks a dozen, I really appreciate this guys!
