I've been doing some research for an internal enterprise application project and I'm considering the risks of adopting a non-web-based approach.
What do you think would be good choices of languages/frameworks to develop a "traditional" GUI desktop application? An "old-school" program containing a top-level menu and multiple non-modal screens, containing widgets like buttons, text fields and data grids? Primarily Windows based, but preferably multi-platform?
So far, I'm considering c#/mono/GtkSharp (not sure which fork), but I'd like to get more ideas.
It's been 8 years since my last desktop application project. It was c#/.net 3.5/windows forms.
I would, however, suggest either Java Swing or Java FX (depending on how fancy your application is going to be and/or whether it will have modern multimedia.
In my experience, one can develop and ship high quality enterprise grade desktop applications - not only ship, but also maintain them for a period of over two decades.
