How to build box

[Dzi]

Hello!

I have some web site box which other webmasters can include in their web sites. Box shows last 10 software added on my portal (http://www.download.hr/about/webmasters/lastsoftware)

Box is build in php and I want now to build same box but in javascript (so others can paste javascript code in their pages and include box)

How can I do that? Can You give me some tips, links or tutorials because I don't know javascript

Is there a reason behind wanting to use javascript?

I bought adversting space on one blog servis, and their pages are in asp, so they told me that it would be better if i have javascript version of box (javascript inclusion like in google adsense adds or something like that)
