I personally don't need a GUI but want to be able to have qemu
display nicely no matter if i'm on a framebuffer console in linux, or if
i'm in X11 on whatever OS, etc. 

Perhaps look at http://www.ggi-project.org/links.html for Toolkits and
Windowing-systems one can use for building a GUI.

There is mesaggi if you'd want to use GGI as a backend for an openGL
implementation. I'm personally not familiar with it, though.

The easiest way to get 2D acceleration in X11 is to use XAA et al.
GGI's display-x is generally as fast as your Xserver's 2D primitives.
