What programs to use?

[cheater1]

I want to create something like a drawing board, where the user can draw, like paint. It doesn't need to be complex like paint. Just need the area to draw lines that follow the path of the users mouse pointer. and the option to change the color of the lines.

Right now my level of knowledge on creating a website is at 0, but I'm planning on learning what ever language needed to make this work.

Also, my dumbest question.
If I used HTML or any other language as the language for my website. Can't I incorporate CSS, flash, PHP, ect. on to it too?

Thanks a lot
