Does anyone know of some easy to use software that will allow me to see what some changes to our exterior will look like before we make those changes?

Currently our house has board-and-batten siding. We plan to cover it with stucco and use some synthetic stone trim. I've been debating the amount and placement of that trim. I think it could be simply stunning -- or overdone and gaudy. If I could scan in a photograph of the different facades of the house and out the new siding on them I would be in a better position to decide.

So, does such software exist? Is it easy to learn how to use?
