Chatroom widget for a free site?

This is basically just an idea right now but if I wanted to put a chat room on a website that basically only allows Flash and Java, and I don't know either language so it would have to be a copy-paste or link sort of thing, how would I do it?

You have to just select that from content box and put there. It don't require any language knowledge. I also created a website using :)

Oh, there already is an option to do so? *sheepish grin*
