have you tried Tkinter's built-in _register method?

>>> import Tkinter
>>> w = Tkinter.Tk()
>>> help(w._register)
Help on method _register in module Tkinter:

_register(self, func, subst=None, needcleanup=1) method of Tkinter.Tk 
instance
    Return a newly created Tcl function. If this
    function is called, the Python function FUNC will
    be executed. An optional function SUBST can
    be given which will be executed before FUNC.

>>> def func():
...     print "Hello"
...
>>> name = w._register(func)
>>> name
'10768336func'

>>> w.tk.call(name)
Hello
'None'
