Sure, although they may not be able to support some features. The OS X
port doesn't even need X anymore.

This needs to be considered on a case-by-case basis. If something only
exists on linux, does it even make sense to add it to gtk+? And if it
isn't possible to implement on some platforms, this has to be reflected
in the API (with correct failure modes for the non-supported case).

This is also a case-by-case thing. For instace, much of modern rendering
platform specific code goes in cairo. Window handling stuff go in gdk.
Native print dialog support go in gtk.
