Glade is just a tool for building window/widget layouts for the GTK+
toolkit.  It does not do any drawing itself, nor can it be used to do
so.

What you're looking for is GTK+ and its backing libraries GDK and Cairo.
They will let you do all the drawing you want, much as you would with
any other graphical system.  You can use Glade to design your window
layout, with a DrawingArea where you want to draw your automaton, and
then use calls to the GDK (or Cairo, if you don't need to target GTK <=
2.6) API's to do your drawing.
