As seen in the Wachmen:motion comics or the new Marvel Spider woman motion comics....

What're the steps to make one? Can any existing Graphic Novel be scanned in and made into one, or are they created from scratch?
what program(s) are usually used? Anyone have any good reference book/tutorial?

I have a five page short story that I would like to turn into a graphic novel and then into a motion comic... where should i start?
