[Tkinter] User interface for stock portfolio optimisation

[Fourchelangue]

Thank you for your help @joe_momma. I had a look at the other post, but unfortunately, as I have told you, I am a real beginner and this is hard for me to understand and adapt to my particular case. Could you provide some more guidance on how I should do this concretely please? Maybe you know some videos online to make this particular thing or maybe you could give me some hints yourself?

Do you think I should repost it in the "Homework" section to look for help maybe?

Thank you.
