Yes, tkdnd could be added to a standalone app, inserted into the tkkit 
if you use ActivePerl/PDK, or otherwise as I believe Vadim has an 
alternative solution.  For tkkit, I have posted instructions to this 
list before about adding modules.  It does require an ActiveTcl 
installation (although it would be possible within Tkx itself ... it's 
slightly more complicated than the Tcl script I sent).

The BWidget dnd model would work with Ttk (tile / themed Tk), but you 
would have to extend the code for that.  Tkdnd is a C-based extension 
that works (via overlay bindings) for any widget, but also ties directly 
in to the native dnd for the platform.  It's not yet ported to OS X, but 
someone is working on it.
