Ouch!  You definitely want to rethink that at some point, but I 
understand that UI redesign for "working" applications isn't easy.

Classic Tk widgets allow changing the background, but themed Tk widgets 
require the use of styles.  Even then, you don't always get control of 
the background color as some native engines don't support it (easily).

Yes, that indicates you are using an 8.4-based Tk.  We now ship with an 
8.5-based Tk, where the 'tile' extension was added to the core.  This 
added the native themed widgets, as well as combobox, notebook, sizegrip 
and a few other new widgets.  See http://wiki.tcl.tk/10630 for a full 
list of core changes in 8.5.
