Hi!
I see you've made a GUI! This is something rare in the Python world. I'm quite sure visitors would enjoy seeing what you've created. It doesn't have to be fancy for visitors to enjoy seeing it. I LOVE seeing what beginners make... I learn a lot from beginners, from simple GUIs, and so do others. Honest!
I appreciate you've added PySimpleGUI to the repo name 
Very nice! Now visitors will KNOW that you've got a GUI, so show it to them. Instructions are in the Cookbook on how to do this.
