I have a wxPython based app which I am porting to Mac OS X, in that I need to show some alerts which should look like native mac alerts, so I am using pyobjc for that e.g.

import Cocoa

import wx

app = wx.PySimpleApp()
frame = wx.Frame(None, title="mac alert test")
app.SetTopWindow(frame)
frame.Show()

def onclick(event):
    Cocoa.CFUserNotificationDisplayAlert(0, 3, 0, 0, 0, "Should i mix wxpython and objc", "hmmm...", 
                                         "Cool", "Not Cool", "Whatever")

frame.Bind(wx.EVT_LEFT_DOWN, onclick)
app.MainLoop()

Is there any thing wrong in such mixing of wx and objc code, any failure points ?
