Ummm... I know Javascript, but if you are thinking of coding a game in it, I think I must inform you that you are seriously out of your mind. Javascript is fine for making little tools and nice little DHTML effects, but coding a game in Javascript is close to impossible and not a smart thing to do.
I hate to tell you this, but it's completely unlikely that you are going to get much help with this. Your best bet would be to fire up RPG Maker, and make it that way, or to learn a real coding language, and build the game yourself. Visual Basic is a pretty easy language to learn and use, and I would probably advise using that. If you are a complete newbie programmer though, I might suggest starting with C, as I don't think it teaches as many bad habits as VB.
