function that will retrieve at some future stage the result of the last
press (if any) of Get coordinates button. Is that what you want?

To illustrate (?) Professor Ripley comments, I send you an example (stolen in
various places...).
Note the tkwm.resizable(tt, 0, 0) directive that prevents the window rescaling
