The compiler can use an internal assembler or an external one.
You can cross-compile if you want, but then you need the correct linker
for the target OS.

Yes, see Xlib.

It is probably possible using xlib, but using GTK or so would definitely be
easier.

Don't forget that X uses an event loop, so emulating a Graphics unit is
not going to be easy.
