Bit of help with a python script?

Hi guys, my mam is a bit of a noob, she can figure out how to use Skype on linux, but the concept of multiple instances is too much, so I often see two or three skype icons on her laptop.

I found this script to run from the Skype icon that checks if there's a current instance running, and focuses the current instance if there is, otherwise launches Skype, the problem is, it doesn't focus the current Skype window if it's been closed to the menu bar:

#!/usr/bin/env python
import dbus
import sys
import os

try:
    # Try and set skype window to normal
    remote_bus = dbus.SessionBus()
    out_connection = remote_bus.get_object('com.Skype.API', '/com/Skype')
    out_connection.Invoke('NAME mySkypeController')
    out_connection.Invoke('PROTOCOL 5')
    #out_connection.Invoke('SET WINDOWSTATE MAXIMIZED')
    out_connection.Invoke('SET WINDOWSTATE NORMAL')
    out_connection.Invoke('FOCUS')
except:
    os.system("skype")
    sys.exit()

Any python gurus out there help me out?
Even adding a simple GTK popup with an OK button saying "Skype is running, check the taskbar!"
I tried something like the answer in this post but didn't succeed in the end.

Cheers!
