admin control for a page template

Hay guys. not sure if this is the right place but here goes.

I have created a custom page template in which I do some funky php to load streaming video, at the moment I have some html drop down list box and a submit button to let the user select a different stream to load, that submit is then sent to the page and on reload the new stream plays.

What I would like to do, is create an admin control where I can enter a list of names.

I then need to access this list of names from my custom template page to populate the select box.

Can some one show me a basic example of createing an admin control that saves some data to the database.

and if possible an example of pulling that data out into a custom page.

thanks.
