问题
Want to make the desktop environment as the application. Is it possible? No need to say that I need a window Manager and other things... I know that it is easier to write on Qt, but I need it to run the application as the environment.
回答1:
You could spend many months or more probably several years diving into the details of X11 and of EWMH.
I don't think it is worth your efforts, notably because several Linux distributions are giving up X11 in favor of Wayland.

I recommend using Qt or SDL or SFML, even for a game.
