Thanks. I'll keep that in mind.  Here's what I came up with for
buttons:

class MyButton(wxButton):
    def __init__(self, parent, ident, *argt, **argd):
        c = None
        if argd.has_key("command"):
            c = argd["command"]
            del argd["command"]
        wxButton.__init__(self, parent, ident, *argt, **argd)
        if c:
            EVT_BUTTON(self,self.GetId(),c)

The usage of MyButton() is identical to wxButton() except you
can add a command=self.foobar:

    MyButton(self,-1,"Button Text",command=self.buttonCommand)
