Is doesn't matter what you use to collect
the data (although I wouldn't use CW_FORM
either). The important thing is that you store
the information on the form *outside* the program
so you can collect and return the data from the
widget definition module (after the XManager
command). By "outside" I mean in some kind of
pointer location.

You can either read my book on the subject of
writing dialog form widgets (:-)), or you can 
look at a simple example of such a program. Here is
one that goes with the book:
