(maybe advanced) Web Design/Development/Programming Question?

Hello and thanks, I know HTML and basic CSS, but these can not fill my needs, I need to know how to do the following:
I’m building myself a graphic design portfolio, I can easily create a web layout, but it’s the features I really need help with.
See, as I only know HTML, for me to update my portfolio I would need to add, move things from page to page if it goes over a certain number, which then involves create new pages and new links….
It’s a lot of work, but I’ve seen other web pages that are easily updatable and the features I need done automatically after me entering the required data.

adding to what just “JR” already said

keep in mind that doing so from scratch is called Web Programming and since i guess you don’t know much about it you can use some PHP, CMS or blog systems like wordpress just for start to see how things are , installing wordpress or any CMS on your local server is really a good start

but for developing your own CMS you need to study a lot about web programming first place to start is to get your Local web server with MySql and PHP running
Xamp is the best Program ever it means X= any operation system A= Apache M= Mysql P= PHP
you can download it here

http://www.apachefriends.org/en/xampp.html

install it and you will get all of those web applications
open up the xamp control panel and run Apache (Web server) , Mysql(database system)
you need to use your browser to point to http://127.0.0.1/ or http://localhost/ to get access to your local web server and will see some examples of what is web programming and what you can do with it
next step is to get adobe Dreamwaver witch is your web development application and start coding PHP some how like Microsoft visual studio

look for some PHP beginners tutorials
