## example implementation:

import tkinter as tk
import tkSimpleDialog

class MyDialog(tkSimpleDialog.Dialog):

    # this method overrides the one in the Dialog class (below)
    def body(self, parent):

        tk.Label(parent, text="First:").grid(row=0)
        tk.Label(parent, text="Second:").grid(row=1)

        self.e1 = tk.Entry(parent)
        self.e2 = tk.Entry(parent)

        self.e1.grid(row=0, column=1)
        self.e2.grid(row=1, column=1)
        return self.e1 # initial focus


    # this method overrides the one in the Dialog class (below)
    def apply(self):
        first = int(self.e1.get())
        second = int(self.e2.get())
        print(first, second) # or something
