(I think you mean PyGObject, since PyGTK doesn't support GTK+ 3.x.)

Isn't info_window.show() doing what you want?  Newly-opened windows
appear on top and get keyboard focus.

If the window was already visible, and you just want to bring it to
front, try info_window.present().  The window manager (i.e. gnome-shell)
may feel free to ignore your request, on the grounds of focus stealing
prevention -- in that case you'll get a notification about the window
wanting attention.
