Yes, the programming model is too different.

Have you looked at gnocl?  It tries to keep the Tk model as much as 
possible.  This could make the porting easier...

That is an interesting idea (at least for the "look" side of things). 
Have you looked into Tk_Theme (by George Staplin)?  It has a 
theme::frame and theme::label widgets.

Where are the SNav screen shots?  I would love to see them...

Probably less of a problem than trying to get the Windows look like was 
done in the past ;-)



Thanks for you comments Ian.  Please if you can keep an eye on this 
thread I would really appreciate.

Best regards,
