No, this has not been implemented in GNUstep. I would suggest that you
build up an NSBezierPath instead and use this to draw. Other parts o
Display Postscript are available, but we are moving away from it as the
main drawing interface.

Interfacing with C should cause no problem. For C++ I would recommend
that you wait until gcc with mixed c++ and Objective-C support becomes
available for Windows.

Nicola has been researching on this recently. Best he comments on this.
