How to build a new CMS website

[stefsegers]

Hi All,

I want to make my old website into CMS. You can see the example at www.stefsegers.com
First of all I want to make a picture gallery, but since I have so many pictures I want to upload the pics and enter the gallery name and select the directory where the pictures are uploaded.

1 How can I make a list of my galleries and for the ones with the less click (3 galleries) put a thumbnail with description on top.
2 Can I then use SimpleViewer to view these pictures?
3 Is it possible to put an agenda like I have now on CMS?
4 Audio and Video tracks are essential to my website and need to have criteria like trance/club (genre), date, hits etc. Is that also possible to make?

I hope some people can help me out here with some or all ... CMS look really good!
