Available (RSN) at http://mini.net/sdarchive/button.bin is a package (implemented using Incr Tcl that provides fancy Tk buttons. By default, Included are images providing "jelly buttons" - but the developer can specify any images for the normal, depressed (sigh :-)) and disabled button states.
The button Scripted Document includes documentation, in the form on an internal read-only Wiki - so for more information download the above link and run without arguments. The Fancy Tk Buttons package is implemented as an Incr Tcl class - so you'll need to have that available. Two very convenient ways of doing this are to use TclKit (a single file Tcl/Tk executable) or ActiveTcl (a "batteries included" Tcl/Tk mega-distribution).
