How can I launch a private Internet DNS server?

If this is question has a simple answer, you're confounding it by not 
asking a simple, concise question.

If you need expert advice that's accurate and guaranteed to work, hire a 
professional. ;-)

1) The simple answer is that you don't need to run your own DNS server,
    you're done. Once you enter the address and server name correctly in
    your DNS registrar's control panel, that's how people will use the DNS
    to find the address of your that (web or whatever) server.

2) If you want to run your own DNS nameservers, you will need to buy a
    book, read the (BIND) Administrator's Reference Manual, and/or some
    RFCs to set them up properly. In terms of your registrar, you would
    enter the names of your DNS servers and addresses as A/AAAA records,
    and set up NS records referencing the names of those DNS servers.

So which is it:

* Hi I'm Jason and I want to create a DNS record so that the world can
   find my web server. How do I do that? (answer #1)

* Hi I'm Jason and I want to run my own nameservers for a bunch of
   irrelevant reasons such as CentOS, web servers and stuff. How do I do
   that? (answer #2)
