There's no need to do this: GtkApplication will stop the main loop if
the application's window is the last managed by the application.

You also don't want to do this. If you want the button to close the
window, use gtk_widget_destroy() and g_signal_connect_swapped() on the
"clicked" signal, so that the window will be destroyed, and if it's
the last window managed by the application, the application will quit.

Don't nest a main loop in the activate signal handler; GApplication
does all the main loop spinning for you.

There's no real need to do this — the OS will collect the memory of
your process at the end of it. It only helps if you're running under
Valgrind, or similar tools.
Ciao,
