Nice. I don't want to discourage you, but that will take some time (for a newbie). You need to understand at-least the following concepts of Qt, to start working on such a thing. Note that there are more than couple of ways to do it, anyway one should understand these.

Just see how much you score.

1. QWidget/QObject Subclassing
2. QWidget Custom Painting
3. QObject Event Handling
4. QWidget Mouse Event Handling
5. QPainter basic usage

Don't you think MS-Paint is easier
