You already have an Apple ID. You created one to participate in the Discussions.
The issue is whether you can get an iTunes Store account, and since there is no iTunes/App Store for Myanmar (unless I'm not seeing it in the list), the answer is, I'm sorry to say, "no". The terms of use for the iTunes Store prohibit you from using any other country's iTunes Store from outside of that country.
If you can find a source for books in PDF form that you can purchase from Myanmar, then as long as they're not copy protected (Adobe has yet to develop or license a reader for iOS that can handle their proprietary copy protection for PDF documents) you can download them and load them onto your iPod for viewing.
Project Gutenberg is a source for books that are in the public domain.
