Of course you were usind Tkinter...

(1) You can use the modal approach (have a look how Pmw are doing this.
(2) Disable all your controls in the main widget when you show the child
window.
(3) "withdraw" the main window (this is not iconify!)

Example:
from Tkinter import *

m=Tk()
m.title("Parent")
c=Toplevel(m)
c.title("Child")
Button(c,text="Hello",command=c.destroy).pack()

c.bind("<Destroy>",lambda x:m.deiconify())
# note we need lambda to get rid of the Destroy argument
#we should "bind", because there are many ways a window can be killed

m.withdraw()

mainloop()
