(I would like to use tkinter. )
I'm going to do my program who convert roman letters to arabic numbers and vise versa.
I'm going to do two buttons and a textfield where you can write in the number or letters and then choose if you want it transelate to roman or arabic , you choose it to click on the arabic button or the roman.
Also i want to do a calculator who can add and subtract the roman letters.

Can someone help me? I don't know how to do it, to put the functions in the buttons etcetc.

Okey, i'll try this!
But i have done a textbox, where you can write roman or arabic and also two buttons, but how do i put in the functions in the buttons and how do i make the things i write in the box connect to the buttons i click?

By tk event handler call back functions
