Doesn't require much setup. You can use your existing design, add articles (new pages) and link to them on the front page. This way, your front page is changing and content is added.
If you have a lot of new content you are adding, if you don't organize it and make a long-term plan, it won't be organized and very hard to manage. You also have to upload all the changes, which requires you to have NVU/Kompozer installed on the computer, make the changes offline, then upload.
These are content management systems (CMS)... made to manage a large amount of content. It would be very dynamic, as in you can login online and add/manage/edit/delete articles, pages, ANY content any time.
You either have to re-create your design in Wordpress/Joomla to keep your current design (which may be a lot of work for not so tech savvy people) or you have to use a template and modify it to your liking... which again, it will require some homework on how to do that.
Considering both options, if you want something you want to publish tomorrow, NVU/Kompozer can get the job done, however, if you are willing to invest some time and switch over to a CMS, in the long run, Wordpress/Joomla would pay off and it would be easier to manage and create/add new things over time.
By the way, Wordpress is straight forward but Joomla is not.
We have an existing website with static pages. We're not particularly IT savvy but we're trying to add a more dynamic section to it with News, information & Articles. Can anyone suggest if wordpress or joomla would be a good idea, or can we continue to use Nvu/kompozer to add news and articles?

Initial thoughts were to add an extension /news.
Hosting account is with Godaddy & I believe Wordpress/joomla is relatively straightforward to set up. But not sure if there is a better way of doing it or if such integration would be problematic.
