You can look in the source code for calls to sys_vgui().

Also starting pd with -d1 -d2 or -d3 prints the gui messages as they occur 
(-d1 prints messages from pd to pd-gui, -d2 prints messages from pd-gui to 
pd, -d3 prints both types).

And pd.tk is where the tcl/tk procs that communicate with pd are found.
