Well, not really. If you wanted to do it that way (and do it right),
you'd have to build all the dialogs yourself, using the TCL windowing
routines, and re-implement the Modal Dialog routine, and write all
the code to handle where the user clicks, etc. From my experience,
it'd be more of a pain than it's worth, but you could do it.

If you want to use dialogs that are resource-resident and use
GetNewDialog and Modal Dialog with them, you have to call
Dispose Dialog after you're done with it. No big deal.
TCL can't handle the windows that the dialogs are in, because
they're not of type CWindow, etc. The best way (for me, anyway)
is to call GetNewDialog, Modal Dialog, do whatever has to be
done, and blow the dialog away with DisposeDialog.

Modeless dialogs, on the other hand, might be worth doing using
the TCL routines.  (Just my humble opinion)
