In order to do that you will have to learn a server-side scripting language.
But - they aren't hard!
If you are familiar with nothing server-side and you are familiar with Windows, I would go to http://www.webmonkey.com/authoring
, look under "backend" and then "databases" and take the "Rugged ASP" tutorial, and the related tutorials. They will give you exactly the kind of code demonstrations and examples you're looking for, I think.
Another WONDERFUL site is www.w3schools.com
And YEAH you can do it. This kind of stuff is not hard, it just takes a little bit of practice - like skateboarding.
