Incorporating Flash menus to sites

I was considering producing a site including tutorials, my portfolio, and well, the normal stuff for that type of webpage, but I was wondering how you could incorporate a flash rollover dropdown menu to a mainly html page. I could use layers in Frontpage but that makes the page virtually unaccessable to those not using IE. Tables solve this problem but the flash stage size > the main buttons, so it would be nearly impossible (at least with my current knowledge) to but anything under the menu.

If anyone has a solution or could be of any assistance could you please aid my cause. The attached files are a primative menu for the site not near completed but the visualize the concept. Thanks in advance to those who reply.
