Conan is the up and coming centralised package management system for
C++ may, or may not, get modules (and so remove the .cpp/.h split)
sometime before the heat death of the universe.
You should add Rust to the list of options I believe.
Not sure whether Go should be added as well, probably Yes.
Python, D, Rust, and Go, all have bindings the the various file
watching facilities in the various operating systems.

It is really a question of which GUI framework you want to use. This is
a situation where a bit of forward planning will help avoid having to
reimplement or hack in silly ways.
The two obvious candidates are Qt and GTK if you want to be cross-
platform. This then leads to the question which programming languages
have good bindings to the frameworks. I am more or less in the GTK camp
now having more or less given up on Qt, however Qt remains a very good
D, Python, and Rust have excellent bindings to GTK. Go has a good
binding. C++ binding to GTK is not bad, but I prefer the D and Rust
Python has an excellent binding to Qt (use PySide2). Obviously C++ has
an excellent binding to Qt since Qt is a C++ library. I have not
properly investigated D and Rust bindings to Qt. The Big Question™ is
whether to use QML or not. I get the feeling the answer is yes you
probably should. The Python and Go binding for using QML are good, I
haven't tried D, Rust, or C++.
