Scaled pop-up window

how would i go about making a pop-up window (no scroll bar, menu, etc…) with a SWF (750 x 700) inside it that is scaled appropriately to the screen resolution of which it is being viewed. i.e. i want the pop-up to fit for multiple resolutions (it is primarily all vector graphics) and if possible, i’d like the button that opens the window to be in flash.

thanks for any suggestions…
