I think you may be completely out of luck here, as colored text
widgets are not really the "IDL way". :-)
A draw widget with text in it is not really such a bad hack
sometimes, especially if it is written as a compound widget.
You can even "hide" a text widget under the draw widget so
you can pick up typing events, etc. This is a little more
than beginners can usually chew, but you seem to know what
you are doing. :-)

No, it seems a rather flimsy excuse. Most of the old timers
here have gotten used to considering capability first and
design second. It's been awhile since we were young enough
to think the correct way. :-)
An alternative may be to use something like Visual Basic
to create some or all of the interface and IDL (through its
Active X component) to display the results. The combination
of VB and IDL can sometimes create promising results.
Cheers,
