What should be learnt first, GUI programming with Qt or game graphics programming with Opengl?

[MrPercy]

After learning cpluplus for 2 years now,i am migrating to learn GUI and game programming with opengl,

but a problem lands in what should be learnt first?

[Thomas1965]

What do you want to do?
Do you want to write GUI apps or games - these are totally different things.
Or do you just want to learn for the sake of learning?

[MrPercy]

i really want to know c++ in depth such that i can tackle dow any programming project for both gui and opengl graphics.
