He is askinng about OpenGL, not DirectX.

Dunno if it is the default, but iirc SDL supports OpenGL on Windows.

SDL has support for OpenGL builtin, so qemu should be able to use that
with only a few modifications.

No one has tried to make an SDL Gui for qemu. SDL guis tend to be ugly in
general.

There is a well supported GUI for OS X called Q, and there are 2 versions of
qemu that use a GTK GUI internally.

Supporting something that runs (or can run) on top of X would catch most of
the platforms that qemu runs on, the only ones I can think of that would need
their own stuff would be Windows and OS X (well OS X has an X server but users
prefer a native GUI there).
