-2. Lägg till en Text widget så att man kan skriva text. **Svårighetsgrad 1**
-3. Lägg till en Scrollbar widget så att man kan scrolla. **Svårighetsgrad 2**
-4. Implementera en oimplementerad funktion i taget och lägg till antingen knappar eller menyknappar så man kan köra funktionerna från programmet. **Svårighetsgrad 2**
