The "lookup_widget()" paradigm comes from a very old time when we had very poor tools and actually it originates from people using generated code from the original Glade tool (Glade versions 1 and 2).
Ideally, as specially as you are using python, your application should be modular. Perhaps you have an Application object which owns the main widgetry created by GtkBuilder after having parsed a Glade file initially, this is different from a global variable. Ideally you can use you object constructor as an entry point to load your GtkBuilder and assign the pointers you need later on to the members you define on your Application object. After that you simply have to pass your Application object to all the callbacks which originate from the user interface, giving you access to everything you need when you need it. This concept can be further extended to be more modular, for instance if you have a preferences dialog/window... it can be defined by a separate python class/GtkBuilder file and reused at will throughout your program.
