Thanks for the clarification and telling me about SSCCE :)

But just a simple thing,,, Can I call a method of another module while 
creating a GUI.

For example
  C = Tk()
.....(Some more lines)
self.sendbutton =Button(self.f2, width = 5, height = 2, text = "Send", 
command = <ANOTHER MODULE>.<METHOD OF THAT MODULE>)
         self.sendbutton.pack(side = LEFT, padx = 10, pady = 10)
.....(Some more lines)
C.mainloop()


Because I am getting stuck in a loop. The client is keep on connecting 
to server without creating a GUI.
