Yes, the selectable() method on widgets determines whether the cursor
will move to a widget, so you could make a Button subclass that returns
False from selectable() when the button should not be selectable.
You will also have to intercept mouse clicks for it to be a complete
solution. Look at the code for the Button class, it's not very complicated.
