Who are all these masochists using Tkinter? There are a ton other APIs to consider, and even more if one wouldn't mind updating an old one to be current (think XUL). I think this is the second or third thread where that particular toolset has been named as if it were the only alternative to Electron

I hate Electron too but is everyone really so new to the game that they do not remember desktop programming?

There's Swing, GTK, QT, JavaFX (maybe), WinForms....
