Well, you can always go and look for adobe flex, adobe flash or even microsoft silverlight, which in the next version will support desktop applications as well.
Other types of frameworks currently do not build so well under desktop/web environments.. Take .NET for example, which can be used in so many set of environments, but there are limitations if you want to use it for mobile, web, desktop or XNA, everyone has his own set of tools.
That is mostly resumed in the capability of the desired environment, since you can browse a web page in an iphone, which does not have the same capabilities of a desktop or even laptop PC.
Seva is telling you how this is normally dealt with. MVC is a good start.
