See the example scribble-simple in the gtk-- package.  It demostrates
a drawing area, allocation of colors and pushing pixels.  
Note that you should also consider canvas or opengl if you want
to do something which requires more than primative operations.
The GtkDrawingArea ia the basic widget you should use.  

Further questions of gtk-- would be best answered on the gtk--
mailling list.

Hope it help.
