1.1.5 What is GNUstep’s position towards KDE and the GNOME project?

You can use GNUstep with GNOME and/or KDE. GNUstep displays on top of X11. You can still do programming in C (since Objective-C is just a super-set of C), and when GCC gets around to it, you’ll be able to mix C++ and Objective-C code in the same file.

GNUstep, is much more than a window manager or desktop environment. It frees you to develop cross-platform applications without the work of developing an OS independent framework from scratch. It gives you lots of basic functionality, from font panels to Unicode strings to distributed objects.
