because printing will be very small for the user.
A GUI will solve that problem, and provide possibilities to select time
and proper buttons.

- Find a tutorial on e.g. Tkinter, one with 'grid' positioning (not packing).
- The geometry will let you decide how big the app window will be, the next 5 items must fit in (width, height)
- Start with 3 Labels for the words
- The A Entry text box to type the duration (user)
- And on the fifth row (actually # 4) a button that says 'start'. When you press it it changes to "stop"
pressing start will validate the entered duration and start the show.
