GDK is a lowlevel windowing lib while libart provides PS like, fast rendering 

Libart is a high-performance rendering library that provides a rich imaging 
model. Libart's imaging model is
a superset of PostScript, and it adds support for antialiasing and alpha 
compositing (transparency). 
Libart is used as the core rendering engine for both the GNOME canvas and the 
GNOME printing system.
It uses sophisticated techniques such as microtile arrays and sorted vector 
paths to maximize performance. 
Libart provides a wealth of vector path-manipulation operations, affine 
transformations, antialiased and
alpha-composited vector path rendering, and functions for manipulating B├ęzier 

I don't know libart in great detail, but it looks promising. It could perhaps 
be used to implement sth like CoreGraphics for GNUstep.

There is already a working Java bridge for GNUstep!
