I would suggest that nearly every person on this website is a developer. Both C and C++ let you shoot yourself in the foot quite easily, but at least C++ has RAII.
If you're referring to Rust, it's just not there yet for anything serious: https://areweguiyet.com/
I looked into this as well, but both libcosmic and cosmic-applibrary are still a WIP -- that's self-described, as well! There is no, for example, Qt or GTK in the Rust world yet.
I'm sure that it will be a reality at some point, but it's not there yet in a format a third party could use without it being obsolete after a few months. I am hopeful, though!
good luck avoiding c++ software on the desktop. FWIW, c++ has many more features than plain c for improving safety and reliability (for example shared_ptr) if that's your concern.
