Another way  might be not to destroy the widgets each time, but to hide them
under the others. I did something similar by creating different subclasses
of Frame and gridding them all in the same place of the main window and
then call tkraise() on the corresponding Frame widget when a new item is selected.
Example:

from Tkinter import *

class Pair(Frame):
    def __init__(self, master, label='pair', **kw):
        Frame.__init__(self, master, **kw)
        self.label = Label(self, text=label)
        self.label.grid(row=0, column=0)
        self.entry = Entry(self)
        self.entry.grid(row=0, column=1)

root = Tk()
root.grid_rowconfigure(0, weight=1)
root.grid_columnconfigure(0, weight=1)
pair1 = Pair(root, label='pair1')
pair1.grid(row=0, column=0, columnspan=2, sticky='news')
pair2 = Pair(root, label='pair2')
pair2.grid(row=0, column=0, columnspan=2, sticky='news')
b1 = Button(root, text='pair1', command=pair1.tkraise)
b1.grid(row=1, column=0)
b2 = Button(root, text='pair2', command=pair2.tkraise)
b2.grid(row=1, column=1)
root.mainloop()
