Building a client using OpenGl or?

Question

OpenGL

Good day.
There is an idea to rewrite the client for one of the online games (so far it is c # wpf) in the form of a full-fledged graphical application. I just want to make some kind of interactive menu, with animation, lighting, well, in general - like in games. Where should I look to implement my plan? Any game engine or is it too much for my purposes ?
