python(tkinter) confusion

[googled first]

This type of thing works in python

dict = {}
boxes = ["box1", "box2", "box3", "box4", "box5"]
for box in boxes:
	print box, "give it an integer"
	dict[box] = input() 
print dict

This does not

from Tkinter import *
root = Tk()
dict = {}
row = 0
boxes = ["box1", "box2", "box3", "box4", "box5"]
for box in boxes:
	lbl = Label(root, text = box)
	lbl.grid()
	entry = Entry(root, width=30)
	entry.grid(row= row+1, column= 0)
	row += 2	
for box in boxes:
    dict[box] = entry 
def gcodeme():
    print dict
Button(root, text = "Make it so", command = gcodeme).grid(row = 17, column = 0)     
root.mainloop()

How do you get useful values from the entry boxes. Maybe the whole concept is bad?
