Perhaps the easiest way is to never use the default top level window:

from Tkinter import *
DefaultTop = Tk()
DefaultTop.withdraw()  # Never to be seen 

def makeNewWindow():
   mstr = Toplevel()
   f = Frame(master=mstr)
   ...

You can still do
  DefaultTop.mainloop()
when it time to turn control over to the main event loop
