move a label gradually/smoothly

Question

Hi Friends,

i want to move a lable gradually on a form application.
it is something like this,

once i click on the button, a colored lable should move from 1location to another location(locations are predefined:say X1 to X2) smoothly.
smoothly in the sense, it should not jump from one location to another. but it should move gradually/smoothly in a predefined path.

if anyone can please give me a solution..

thanks,

charith
