You could use an IntVar just as easily (and avoid the
string conversion) but I used StringVar because a string
is more easily formatted. The key thing is that the Tkinter
Var objects allow communication  between two widgets
automatically without you having to do anything other
than assign the same Var to each widget.

It was your comment that you wanted something like Scale
that triggered the idea - that's how Scale works too.
