Thanks for your input. It coincides with my impression about Qt and Gtk. Years ago I made an application (for myself) with Qt and C++ and it was kind of a pleasant experience. I was only reluctant because I would like to not use C++ in my free time.. I will however consider this again and maybe see what bindings exist for Qt.
I don't think Flutter is an option for me. I would then rather go the JS/Electron route. It just makes no sense to learn Dart to me.. the only use for it seems Flutter.
Yea, I only mentioned flutter because it is there and is growing, but if I wanted to ship a desktop app quickly to get moving, it'd be Qt for me. I personally love C/C++, but understand not everyone does, but for installed desktop apps, C/C++ still just makes the most sense to me.
I know Wireshark moved off Gtk to Qt for a variety of reasons, but some of their key points from what I remember was Gtk was falling further behind on issues, current trends and platform support whereas Qt has really kept up and keeps evolving with the market.
