If you are just learning to program, writing your Sugar activity in Python would save you loads of trouble. 

It is possible to write an activity in any language (I know, because I did it) but you do have to be proficient in the language you want to use, and be able to map general advice into working code. 

For C#, the framework that Lionel's tutorial describes already goes a long way, the hardest part is done. But extending it to fully support a Sugar-like GUI and collaboration is going to be your problem, since you are one of the very few (if not the only one) who want to write an activity in C#.
