turn dashboard widget into webapp

I have a dashboard widget that I'd really like to see as an iPhone webapp (and maybe eventually a real app). I didn't write this widget, so I'm only curious to so how it would work on an iPhone. I can edit in in dashcode- and dashcode does both widgets and webapps- so how do I change one to another? The problem is I don't really know html/xml that well, so I can't really port it to objective-c. However, I think that the widget is almost perfect as it is for the iPhone, so how hard could it be to turn it into a webapp?
