Oh, it can be done, but while strength is easy to build up if you just start using the other hand exclusively and have some time, coordination's an utter bitch. Some people are better at it than others, but I spent many hours during class writing nonsense with my left hand for practice because I was so bored, and it's still completely illegible and is insanely frustrating to do. When I injured my right hand, I spent the next month telling my parents to forge my signature and stuff like that.
