To get an undecorated window (no window borders), use
[method@Gtk.Window.set_decorated].
All top-level windows created by gtk_window_new() are stored
in an internal top-level window list. This list can be obtained
from [func@Gtk.Window.list_toplevels]. Due to GTK keeping a
reference to the window internally, gtk_window_new() does not
return a reference to the caller.
To delete a GtkWindow, call [method@Gtk.Window.destroy].
