How to make iPad app for business presentation?

Hi! My boss wants to do a presentation on an iPad. He wants me to create something that behaves like an app, but exists only on that iPad (not in iTunes). He wants to be able to call up a PDF, some videos, some images, etc. All native on that iPad, no internet connection necessary. Is there a way to easily do this without being a developer? I have design skills, so an app that is customizable would be ideal. I was looking at Adobe InDesign for this but I don’t think I will have the time to get approved by Apple as a developer. Needless to say, this has to be done in a very short time frame.
