Is jQuery best choice for window that must control itself?

Is jQuery best choice for window that must control itself?

After posting once about this and realizing the reply would not work, I am rephrasing.

The link that will trigger the new window I want to display does not have any JavaScript or CSS capability at all. It is a hyper-linked area on a Flash object that must call a new window smaller than the Flash object (which is full screen) and re-position itself on the screen. Just self centering might work but more control would be fabulous. There is no parent-child relationship here. I can't bury a DIV inside the Flash object and then display it. I could tack variables to the URL that creates the new window, but that's all. The new/smaller/positioned window will simply display a video or image and feature a close (self-closing) link. I have enough control over what's on the Web server to do CSS styling.

Of all the approaches I've seen, jQuery seems closest. I just need some direction on which parts to study. I'd like to post a link, but if my manager sees this he'll have a total meltdown. Corporate paranoia.
