It's very friendly. You can open an existing image or scan one directly into the program. Then select from a variety of tools that shrink, stretch, magnify, move, and swirl the parts of your image you sweep the mouse across. Deformer is very easy to use to achieve special effects, and an easier alternative than using a GIF animator to achieve these results. It's available as a fully functional 15-day trial, with a nag screen.
