MODDERS NEEDED!

Hey guys! you may know me form the shadowlands Medieval texture Pack, but today is a different matter. I watched Howl's moving castle last night, and i loved it. If you aren't familiar with the anime, read a movie synopses or something. But i need a modder because i want to make a mod that allows a player to build a home, and then craft calcifer ( the talking fire guy) so their house gets up and moves! the fire place can be made with wood.

Recipes:
Calcifer
F=Fireblock E=Ender eye

Fireplace:
W=woodplanks E=empty

I have no idea how to make a mod, so i ask that somebody tries. And i have no idea how you'd make the house grow legs. Oh well. bye.
