Try this:

from Tkinter import *

class MyDialog(Frame):

    def __init__(self, parent):
        Frame.__init__(self, parent)
        self.parent = parent
        self.pack(fill=BOTH, expand=1)
        self.parent.title("MyDialog")
        Label(self, text="Value").pack()
        self.e = Entry(self)
        self.e.pack(padx=5)
        self.b = Button(self, text="OK", command=self.ok)
        self.b.pack(pady=5)

    def ok(self):
        print "value is", self.e.get()

root = Tk()
d = MyDialog(root)
root.mainloop()
