Do you actually want to _animate_ them (ie: have the buttons visually shrink and
move across the screen), or do you just want them to vanish and appear in the
new place?

In Tkinter, placing an object on the screen (using grid or pack) is distinct
from creating the object.  You can use .grid_forget() or .pack_forget() to
ungrid or unpack an object, so that it is not displayed, but it still exists. 
And/or you can just recall grid/pack with different arguments.

eg:

>>> from Tkinter import *
>>> tk = Tk()
>>> b = Button(tk, text='Make')
>>> current = [0]
>>> def make():
...  c = current[0]
...  Label(tk, text='Entry %d' % c).grid(row=c, column=0)
...  Entry(tk).grid(row=c, column=1)
...  b.grid(row=c+1, column=1)
...  current[0] = c + 1
...
>>> b.config(command=make)
>>> b.grid(row=0, column=1)
