Creates a new #GtkWindow, which is a toplevel window that can
contain other widgets. Nearly always, the type of the window should
be #GTK_WINDOW_TOPLEVEL. If you’re implementing something like a
popup menu from scratch (which is a bad idea, just use #GtkMenu),
you might use #GTK_WINDOW_POPUP. #GTK_WINDOW_POPUP is not for
dialogs, though in some other toolkits dialogs are called “popups”.
In GTK+, #GTK_WINDOW_POPUP means a pop-up menu or pop-up tooltip.
On X11, popup windows are not controlled by the
[window manager][gtk-X11-arch].
If you simply want an undecorated window (no window borders), use
gtk.window.Window.setDecorated, don’t use #GTK_WINDOW_POPUP.

All top-level windows created by gtk.window.Window.new_ are stored in an internal top-level window list. This list can be obtained from gtk.window.Window.listToplevels. Due to Gtk+ keeping a reference to the window internally, gtk.window.Window.new_ does not return a reference to the caller.
To delete a #GtkWindow, call gtk.widget.Widget.destroy.
