Qemu is using SDL, as this is a very portable library/framework. I'm not sure, 
if SDL uses DirectX on Win32, but I'd rather think it does not. Of course one 
might want to check this and maybe have a look at the SDL mail lists, if 
DirectX was discussed there.

There already are a few projects for external qemu GUIs, but for an internal 
GUI it would have to be done in SDL, too, as to not introduce further 
dependencies. Please keep in mind that qemu is ported to many platforms and 
therefor the code would have to be very portable anyways.
If you're keen on doing a GUI in Lazarus, feel free to do so, but have a look 
at the ml archive and some existing GUIs first.
