Yes, it won't be hard, but it is also not that straightforward, because 
XCB is a bit lower-level compared to Xlib.

Exactly that is the problem. It is old and clumsy (state-of-the-1980s) 
and I suspect that Wayland will eventually replace it. Xlib and the X 
server will remain there for legacy applications.

Wayland is still alpha, however I would consider at least looking more 
closer at it. Currently it uses OpenGL ES (will use OpenGL later) and is 
oriented towards the future of Linux graphics. Two of the leading Linux 
distributions (Ubuntu and Fedora) stated that they will switch to Wayland 
in one of the coming releases.
