Is it possible to make a custom Desktop buddy in Flash?

This will sound completely Nerdy but im working on my new computer that i am building myself and i thought how cool it would be to have an AI run it. It started as a joke and then i remembered that for christmas i had a tree as a desktop buddy/decoration. So i thought to myself that it would be awesome to have a desktop buddy for my new computer. I drew the character out and will soon put it in flash 8 pro and animate her. I just wanted to know if its possible to make it animate on my desktop in flash. Im trying to avoid 3D as much as possible. Would i need any other programs and could it be done on my PC and Mac.
