Honest question: What's an easy-to-use, popular cross-platform framework with bindings to a sane language? Something like QT/GTK to Python? I hate Electron, but what's the alternative? I used wxWindows back in the day, with Boa Constrictor, and I loved that workflow.
So I don't know about the definition for popular or sane languages but FWIW Lazarus is a free framework for producing truly portable, native applications for Windows/Mac/Linux/Android/iOs from the same code project. Think FOSS child of Delphi from back in the day.
It's a pity, because Lazarus does seem fantastic for desktop application development...
