You didn't mention the ways you tried. You can of course use C++/CLR, but I wouldn't recommend it. Qt Creator doesn't do a great job of editing that mess, and I've found that mixed mode debugging (i.e. debugging a native application with some CLR objects thrown in) can be unreliable.

ActiveQt has an example of wrapping a .NET object (http://qt-project.org/doc/qt-5/activeqt-dotnet.html). ActiveQt can wrap COM interfaces in general, and it's generally possible to expose managed objects as such.

If you're not interested in using ActiveQt, you can do it by hand. Take a look at this experiment for inspiration: https://codereview.qt-project.org/#change,73047
