Sounds like you should get the Widget Creation Library.  It provides
a CvtStringToWidget converter so you can do this type of stuff in
resource files.  It also provides a CvtStringToCallback converter
so you can bind callbacks in resource files.  And of course it also
provides CvtStringToClass and CvtStringToConstructor converters
which allow you to delete every line in your source which looks like
this:
	XtCreateWidget( ... )
	XtManageWidget(... )
	XmCreate....(...)
	XtManageChildren(...)

All that sort of thing then gets put into your resource file(s) and
your C code ends up being nothing but very simple initialization
code and your callbacks and action procedures which actually implement
the application.

Get Wcl via ftp from most any achive server, including export.lcs.mit.edu
in contrib/Wcl1.05 and devvax.jpl.nasa.gov in pub/Wcl1.05
