Web Design Wireframe

What’s the best method to design a webpage (Joomla or Drupal)?
I’m not talking about a generic out of the box solution, but a full web build. I’m looking to build a directory website, which would allow users various levels of access… I’m looking at doing it through either Durpal or Joomla… but really confused which path to take. I want to be able to customize the scripts that will appear on the page as well, & integrate widgets/data feeds from other sources….
Also a take on my process of how to put everything together…
1) define requirements/functions
2) develop wireframe
3) design the creative
4) code it into css
5) code it? (through the CMS or other path?)
does this make sense?
Use a library like JQuery, but build the site yourself.
Your process is the artwork creation, but leaves the programming (the major part of the site) out completely. (CSS is just a statement of the style of the various elements.) You’re going to have to write the HTML (the content itself), then the Javascript (the program that runs in the browser), the server-side program (language to be determined by what’s available on the server – PHP is a pretty universal choice) and SQL to talk to the database (which you’ll need if you have user accounts – which you have to have to let people log in).
Depending on the content of the site, you might also want to use AJAX.
