vb.net button controls and timer control with examples

Question

I would like to draw 2 circles using draw ellipse and move 2 circles simultaneously in opposite direction. These things I want to put it in buttons. Is it possible?. I tried. But it won't work it. In run time I press the first button then the circle will create and move and next press the second button I click then create two circles and move opposite directions and third button,etc until the form size. And another thing how to use timer control in this moving circles.
