What exactly do you want to do?
Why is defining a function too much for you?
I can't see it is your problem since you are a Python programmer
(or you would not ask for metaclass tricks) :-)

Looks like a problem with an interface for users.
Do you want to make the definition
of actions in a GUI simpler for your users?

In the latter case, it is probably simplest to define
a smallish sub-language by a few rules, and create
proper Python functions at initialization time?

Feel free to contact me in private email if I'm right.

p.s.: But please give me a real email address. I have no time
to guess.
