Maybe your executable filename was called main, so that was the default
window title.

If you don't want one of the windows then just don't have one of the
windows. Either remove the MainWindow from your main() function, or remove
the visible property from the window in your .glade file. If you remove the
MainWindow from your main() function, then you might choose to use the
window in your .glade file as the one that you supply to Gtk::Main::run(),
to control the lifetime of your application.

The window is there because you put it there.

I see no actual problem so far, so there is no need for a solution.

I don't know how it could get any simpler than the current example:
