Instead of C I usually use a moderate C++03 subset together with LeanQt. I don't have any of the problems the author mentions. Whatever I implement runs on all relevant platforms, and - in comparison to e.g. Python based tools - my tools also run on old systems and have little dependencies. In contrast, Java and C# caused much more problems with cross-platform applications, where older system compatibility is necessary.
