There's a while loop which will do anything a do loop can,
but...

I think you are missing the point of event driven programming.
When they press the widget it processes a file, if they press
it again it processes another file, and so on.

In other words you don't need a loop to do that. Or more to
the point the Tk.mainloop() is the only loop you need.

You shouldn't need a loop in VB either!
