This doesn't make sense - relative_to is the widget the popup should
point to inside window, so you'd want mbutton here; however
gtk_menu_button_set_popover() will already take care of that, so
passing NULL should be fine.

The popover is not part of the widget hierarchy of window, so the
gtk_widget_show_all() call misses button.

Here is the actual problem - the popover is constrained to the
toplevel window and set up to point to a widget that fills the entire
toplevel - there's simply no space for the popover to appear. If you
do something like:

  gtk_widget_set_halign (mbutton, GTK_ALIGN_START);

the popover should work.
