Clickity click click!

[CDI_]

I had this thought, what if I was to program a music based game similar to DDR in theory (do this when the music does that) but everything has been done realy, except I can't find any REALLY GOOD mouse driven ones (except SiU, but that is diffrent)

So I was thinking what if I programmed a game (maybe in javascript because I know that farily well...) that was mouse driven in sorts, where you clicked a certan area when the you have to along with the beat of the music. (Kinda like DDR with clicking) But it would have to be geared to be used with the mouse, and maybe harder songs would not only have more things to click in a shorter amount of time, but have more places to have to click (from maybe 3 on the easest setting, to maybe 9 on the hardest, or something like that)

Maybe if I get a chance I can whip up a sample style of gameplay and/or some mockups. Any ideas on what programming language I should use? (keep in mind I cannot download and run anything with the computers I use x.x and I have to learn everything)
