Chat Program for Web Site

I would like to have a chat program added to my website. It needs to support both Web HTML chat, and a light Java client. The general chatting features should be allowed, but it needs to link to my SQL server for username info and some special buttons that when clicked pull up pages on the website. *** UPDATE: It seems a lot of people had questions on what the chat program needs to do. Therefore I have an attached Word file that is a brief list of features it needs to have besides the generic "chat" features. I hope this answers most questions, if not I can try and define it more. ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
