That's not a multithreading issue, but just the way the quit method works. Try:

-------------------------------------------------
import time
from Tkinter import *

root = Tk()
b = Button(root, text='Quit')
b.configure(command=root.quit)
b.pack()

root.mainloop()

time.sleep(2)
-------------------------------------------------

When you click the "Quit" button, the GUI stays there until the time.sleep ends. 
root.quit just goes out of the mainloop; it doesn't destroy the widgets. To do 
that, you have to add an explicit root.destroy() after root.mainloop()
