Short answer, no.

Any current web development platform will work just fine

You can always do ASP.NET MVC and return JSON object to iPhone. Now that we have jQuery Mobile, it should be rather easy to do. See one example @ http://yobriefcase.posterous.com/practical-jquery-mobile-with-aspnet-mvc

There are a number of other server-side scripting languages you can build an application with. ASP.NET(C#/ VB / etc), Java, perl, whatever.
