that's another error message, of course...

umm.  what is that line supposed to do ?

if the purpose is to call the sendMessage method of the Chat-
Message instance you're passing to connectTCP, it's probably
better to create the instance first:

    chat = ChatFactory()

    root = Tk()
    b1 = Button(root,text="Send")
    b1.configure(command=chat.sendMessage)
    b1.pack()
    tksupport.install(root)

    reactor.connectTCP('localhost',8886,chat)
    reactor.run()
