Can Gtk be used as a Rendering Libaray ?

[vprasad applix com (V G Prasad [ext 294])]

Hi,
Is it possible to Use gtk as a rendering library ?.
For example, Is it  possible to  pass a Window handle (Gdk window) to gtk to draw a button on the window? 
What I am looking for is a method to get the Gtk widget Look and Feel for my application without going through gtk_main().
 I did look  through the sample applications(testgtk)...
Thanks

vg
