Feature-wise, wxwidgets and gtk+ are a joke compared to Qt.
Electron is not just a joke but a fat pig.
Truth is there's nothing comparable to Qt in the cross plataform world today, unless you are willing to take the risk of Flutter, JUCE, some web technology (which would be regarded as obsolete by the time you ship your product), etc.
Sure, I agree haha. They are the closest but they aren't comparable (although likely for GTK+ one would mention the entire glib stack which is I think comparable to Qt in scope)
