Graphics Adventure type movement

I`m trying to create a movement similar to the old point and click type Graphic Adventures where you click on a point and your character walks over to it.

As I am not too hot with maths it is proving to be a little difficult. What I want ideally is to click on a point and my character walks over to it with a slight easing in at the end of the movement.

Can anyone give me any hints as to how this could be achieved with as little math as possible.

Thanks for any help,
Jason.
