You need to configure the grid, which is done using the methods 
grid_columnconfigure and grid_rowconfigure. The following produces a 
grid with two rows and two colums and places your Button where you want it:

from Tkinter import *
root = Tk()
root.geometry('640x480')
root.grid_columnconfigure(
    0,
    minsize=100,
    pad=5,
    weight=1
    )
root.grid_columnconfigure(
    1,
    minsize=100,
    pad=5,
    weight=1
    )
root.grid_rowconfigure(
    0,
    minsize=100,
    pad=5,
    weight=1
    )
root.grid_rowconfigure(
    1,
    minsize=100,
    pad=5,
    weight=1
    )
B = Button(root)
B.grid(column=0,row=0,sticky='wn')
root.mainloop()
