The Qyoto bindings are well out of date, they do not support qt5, they are pretty much unmaintained, they are not packages for linux and there is not a single opensource project (that I know of) using them.
The GTK bindings are stuck on GTK2, Xamarin has no interest in GTK3 because they want to use native gui tookits on Windows and Mac and linux is not a supported platform for their commercial tools so they have no interest in it. There are community produced bindings for GTK3 but these are not released as stable yet despite it being years since GTK3 was released. Winforms is rubbish on both linux and Mac and unlikely to get any better. WPF is windows only and is not opensource and is it seems unlikely to be any time soon. Xamarin.Forms is mobile only so is not supported on Linux, Mac or even Windows Desktop. Xwt is immature, has limited widget support, Is largely unproven (nothing is using it, except maybe a very little in MonoDevelop) and is abandoned (no commits for 11 months) If you want to produce a cross platform app your best bet is to use an architecture (MVC or similar) which allows you to use a native GUI toolkit on each plaform. This is what I ended up with in my project WideMargin, WPF on windows GTK on linux. I started with GTK on both window and Linux but it look an performed very badly on windows.
