"""Opgave "GUI step 3":

Som altid skal du læse hele øpgavebeskrivelsen omhyggeligt, før du begynder at løse opgaven.

Kopier denne fil til din egen løsningsmappe. Skriv din løsning ind i kopien.

Bruge det, du har lært i GUI-eksempelfilerne, og byg den GUI, der er afbildet i images/gui_2030.png

Genbrug din kode fra "GUI step 2".

GUI-strukturen bør være som følger:
    main window
        labelframe
            frame
                treeview and scrollbar
            frame
                labels and entries
            frame
                buttons

Funktionalitet:
    Klik på knappen "clear entry boxes" sletter teksten i alle indtastningsfelter (entries).


Når dit program er færdigt, skal du skubbe det til dit github-repository.
Send derefter denne Teams-meddelelse til din lærer: <filename> færdig
Fortsæt derefter med den næste fil."""
