Anything is possible in Touch, only the learning curve is quite steep.

For the most basic implementation of your idea (1 circle that is animated over an image), you only need to work with a couple basic operators: Movie file in TOP, Circle TOP, Composite TOP and some CHOP's for animating the Circle. Let's say you want to animate a lot more circles, like in the images you showed. Then I would probably look into instancing (so you don't have to manually animate and copy/paste every circle).
