scrollable button which should scroll along with windows scrollbar movements

[all_vaa]

Hi,
I am trying to do a scrollable button which should scroll along with the windows scroll bar. that is, if the user scrolls towards to right the button should also move . if the user scroll towards left, the button should also move to left.

If the user scrolls down using vertical scroll bar, the button should move down, if the user scrolls up, the button should move up.

i have little idea that i have to use div tag and do this. i am not sure how to achive this.

can anybody help me.

thanks
