you can't submit an html5 application using an url, you have to create an app that lauches a browser (safari...) with your url.
There are some products that helps you this way, eg PhoneGap -> http://phonegap.com/
what about http://www.apple.com/webapps/ ? This is not app store, you don't need AppleID to lounch any of those (only safari and internet connection).
I wan't to submit app over there but I can't find the way.
