If you can provide a framebuffer for each window, back-art can handle
all the rendering for you. If that isn't possible, or if it's too slow,
you'll have to implement the dps rendering (ie. NSGraphicsContext)
yourself on top of some native rendering interface. Unless that native
interface is close to dps, which is very unlikely, that's a lot of work. 

The other part, window management and input handling, is very
system-specific, so you'll have to implement that from scratch either
way. If there's a native window management system you can use, it would
probably be easy; otherwise, this is also a fair amount of work. The
class you'd need to provide an implementation of for this part is
GSDisplayServer.
