She might very well be. Using Gimp for content creation for some time could make her an expert (especially a fast learning and seemingly quite intelligent kid). Though painting itself isn't the main usecase gimp seems to want to support.

Though like so often: Only because a software wants to support a specific target doesn't mean it will be completely unusable for doing everything else.

Funny, my daughter's 13 too and constantly drawing manga characters with Gimp (http://julieflorac78.deviantart.com/gallery/). I've just bought her a wacom tablet, that's much easier.

funny^2 - she just got a wacom tablet for christmas :-). did you get the wheel to work with gimp?

No, but AFAIK it doesn't work yet with Linux. The other buttons work out of the box, though.

Ah ok - she is on win7. doesn't work either, though.

let her try mypaint! it is made for drawing and rocks.

What do you do with the rocks?

Paint.
