php to google gadget for google sites

I just opened a site through google sites. I wanted to install a php fill with a shockwave flash object. Since I read I can't upload .php files to google sites, I wanted to have this php and flash file made intoa google gadget that I can then add to my site. I am not code savvy by any means. Looking for lowest cost and quickest turn around. I attached the zip file which contains the info I want to make into a google gadget. If there is an easier way, I am all for it.
