Languages/QtSharp
Qt# was an attempt to create a set of classes that bind the C# language to the Qt toolkit. The bindings appear abandoned based on the Qt#home page.
The Qyoto/Kimono project are SMOKE based bindings which use the C# generics compiler to generate bindings to Qt and KDE that are very similar to C++/Qt syntax but with the addition of th unique syntactic constructs of C#. Because .NET is a multi-language VM, a variety of languages should be able to access the bindings
