how to convert a WPF ellipse to motion path using C#

Hi all Its hard to explain what I need and I really don't know if that is actually can be accomplished or not. anyway, I have created two circles using blend.

now what I want is to convert the first circle to a motion path then attach the second circle to that path and then generate a storyboard and lastly play the animation.

I want to accomplish this programmatically using C# I don't want to do this from xaml or from microsoft blend. is there anyway I can do this? any tutorial or advice will be apprecia开发者_运维知识库ted.

regards,
