I want to create a tag-based website, and I need a tool that I could use (preferably without programming).

It's a site where a user could pick tags on a certain item. All tags will be placed under a group that they are logically linked to (I will do that by hand). On the other end - a visitor could choose a tag, and then be redirected to a few items on which that tag was selected the most. Besides this, I need to set up a registration form (for the visitors who want to select tags on a desired item).

stackoverflow.com may serve as an example of what I want to achieve. Functionally it is a quite similar approach. I am not sure if further detailing will bring me closer to getting a development advice, but nevertheless - following this template what I would be missing on is:

• ability to categorize the tags; and so they would fit in one page (overall i assume <200 tags)
• box where a user could enter a tag and it would be pending until a certain number of users enter such tag
• ability to limit the number of 'questions' that appear when a visitor chooses a tag - 'question' stands for an item to which users are selecting tags (displayed items would depend on the frequency the tag was assigned - say the top two items)

Which software should I try / How should I go about it? Thank you.

P.S. I have bought hosting account through GoDaddy.com. This is a first website that I am trying to build.
