A "Paint like" application

Question

Hi,
I'm currently programming an application for my sister and I would like to finish before Christmas, but I'm really late. So to complete a part of it, I'm looking for the source of a paint like application. Just something you use to draw line, circle, rectangle, filling it or not, choosing the color... So If you can give me a link to this kind of source, or post some source It would be great.
Thank you.

With a fill option.
