You can define the __init__ method in your wx.App subclass, something like this:
class MyApp(wx.App):
def __init__(self, thingYouWant, redirect=True, filename=None):
self.thingyouwant = thingYouWant
wx.App.__init__(self, redirect, filename)
def OnInit(self):
... something that uses self.thingyouwant ...
