AppLoop.com had an app generator for RSS reader. It created quite a buzz for a while before got shut down by Apple. Currently, there is no iPhone app generator of any sort.

If Objective-C is not your game, you can check out MonoTouch framework if you know VB or C#.

check out: appcelerator dot com

you'll still need a Mac to compile though. I haven't used that particular software (I use Apple supported tools and Objective-C) but I've heard it can do simple apps.

Look at phonegap or appcelerator

I just found Appmakr. It may be what you need.

Hi, I lot depends on what you want to do, apple is notorious about denying apps I had one denied because apple felt like it just would not be appealing enough for apple users.

They had no other reason, and as a developer I can tell you it is a nightmare dealing with apple on submissions.

I am in the process of designing a few app generators, in the near future, but again a lot depends on what you want to do, anything is possible, at least within reason that is.
