Let me expand a bit.
Making an app for iOS, while not overly complicated as far as app development goes, is a much bigger project than putting a book together. You'll need to invest considerable time to learning, then developing your app. If you don't, it's not going to get approved for the App Store; which leaves you rather limited options for deploying it; unless you're willing to go with an Enterprise license and your own app store server.
There are third party tools for creating iOS apps; but you still need a Mac and a developer account to publish the app; or you pay someone else to publish it for you. I could be wrong about that, of course. There are more things out there than any one person could hope to keep track of.
And that is an option if you have the budget for it. There are several companies that will help you create and publish off the shelf style apps for ebooks, catalogs, and other common uses.
In the end, if what you basically need is a book, you would be better off using a book creation tool, either on the iPad, or the HP. It is easy (comparatively) to create and distribute a book for most of the current crop of ebook readers, including the Kindle and iBooks.
Depending on the other types of apps you are considering, similar options are available. Either creating content for existing apps, or paying someone else to create and publish the app for you.
I'm sorry the answer is not as simple as you'd probably like; but I can summarize:
No, you can not create and publish iOS app from the iPad or HP: Or at least not using any of Apple's approved tools.
