How to create an iPhone application starting from an empty project and then adding one resource at a time?

Instead of using the standard Xcode provided templates (view based, window based etc), is it possible to create a full fledged iPhone application by starting with an empty project ?

I mean can one first create an empty project first, and then one at a time, add the main.m file, then import the Frameworks, t开发者_运维问答hen add an xib, add UIApplication delegate class, make necessary connections etc...

Has anyone tried this? It would certainly help one understand the basic anatomy of an iPhone application.

Yes. At least in Xcode 4.2, there is the "Empty" project template with no files, targets or build configurations.
