Another alternative, I think is D-language bindings to QT (or betterC which is a subset of D allowes to use D with C runtime library, while retaining D-s class system, templates and memory safety).

D's team is doing an incredible job of matching C++ compiler specific ABIs, name mangling/etc -- just so D users can use C++ libraries (including templates) directly from D without loosing the features of the language.

Here is also an older video of Walter Bright (2015) talking about the challenges that D is tackling
