Metal is written in C++. Try to display graphics in Objective C or Swift without Metal, going further.

Which UNIX OS SDK uses a C++ GUI full stack?

One could argue for Kubuntu or SuSE, maybe, except KDE isn't tied to a specific OS and then again it uses Qt alongside QML since Plasma, so no pure C++ stack here.

And since you missed to fully read my comment, here it is again:

The KDE desktop shell is QML + C++. The vast majority of KDE applications are QWidgets + C++ without QML.

I like QML but it's not that great for many / most desktop applications. It works better for creating fully custom touch UIs from scratch. The plan for Qt 6 mentions a styling API which is one of the most important missing pieces, and discussion in the comments maybe indicates more ready to use controls.
