Interfacing with C++ is a lot of work and there is no language in existence that can do that effortlessly. Nim and D are the ones that come close. Julia's interoperability with C/C++ is quite poor according to feedback from more experienced Julia users.

.NET does it relativity easy given C++/CLI, and on the native side there is COM, UWP, C++/CX and C++/WinRT.

So any language on Windows able to use COM/UWP, gets those Python libraries, sorry, C++ libraries.

The effort to use Julia FFI to interoperate with them is hardly any different than using Python FFI, with the big difference that in what concerns Julia it would be possible to re-implement them in pure Julia, while the Python community keeps wondering about to write more FFI code to native libraries or finally start adopting PyPy.
