Until now I have only made a few compounds. Some of them require the use

I would suggest to use the compound mechanism. Create the dialog as a
coumpound (I checked with vtcl-1.10 that coumpounds can be made with
toplevels), then create a compound-associated procedure that is passed the
name of a toplevel and possibly the arguments of the dialog.
This procedure will show the given toplevel, assuming it was built with the
corresponding coumpound, and change the contents of some widgets in it, for
example the text of a message. The binding of the buttons is so that their
toplevel is hidden when pressed. Then the procedure just has to do a
"tkwait window $toplevel" to wait for the user to finish the dialog (and
possibly do a local grab on the window).
There may be another possibility, by considering the given toplevel as
a class and creating a new instance of it, because I guess that the
"Window show" command might be able to do such a thing (I have not tested).
I must recognize that all this is rather heavy, but I didn't experiment
to check it -- yet.
