Here is a version that works. The changes from yours:
- Bind <Escape>, not <Key-Escape>
- Bind the key to the root, not the frame
- Define a quit() method that takes an event parameter

from Tkinter import *

class Application(Frame):
     def createWidgets(self):
         self.lab = Label(text="Hello World")
         self.lab.pack()

     def __init__(self, master=None):
         Frame.__init__(self, master)
         self.pack()
         self.createWidgets()
         master.bind('<Escape>',self.quit)

     def quit(self, event):
         Frame.quit(self)

root=Tk()
app = Application(root)
app.mainloop()
