Bleg on Apps development

I would like to create an Android app and an IOS app for my website, davekopel.org. My requirements are: I want to be able to submit the app to the Google Play and Apple Stores, rather than the app being available solely on a third party website. The app does not have to be highly sophisticated; my website has about a thousand html files, and a lot of pdfs, but (except for my three-column home page) all the html files are single column, without a lot of coding. (I recently figured out how to use CSS.) The app needs to be able to handle typical things such as a Twitter feed, RSS, search, YouTube channel, audio and video links, etc. But nothing fancy; I don’t create Flash for my website.

I’m willing to pay, and would prefer to pay a one-time fee, rather than a perpetual monthly fee. So, in light of all that, what web services do readers recommend for me to build the apps?

Update: To clarify my objectives, in response to comments. Basically, I’m looking for something like the apps created by Reason, Cato, or Daily Caller. To give people simpler access to information about what’s new on the site, and to enable them to navigate the site. I’m not trying to put all the full site content itself into somebody’s cell phone.

I realize that anybody can get the same information just by using their mobile phone browser, and visiting the website directly. All my html pages have the barebones coding to be mobile-friendly:

<meta name=”viewport” content=”width=device-width, initial-scale=1.0, maximum-scale=2.0, user-scalable=yes” />

In my own use of Android, I sometimes find it easier to just use the Reason App, rather than browsing to www.reason.com, in order to see what’s new at Reason, and to possible read an article, or watch a new Reason video. All I’m trying to do is provide similar a similar app for my site.
