I don’t think compiling from source is easy even on Linux. Whenever I try it whatever program I’m trying to compile just refuses to compile, even though I seem to have all of the necessary programs for it. I can’t recall successfully compiling anything other than suckless tools, which have basically no dependencies.

No idea. Haven’t used Windows for anything other than games for around 20 years either. How hard it is isn’t really the point, though.
