what programming language should I use for context ad application?

[EditFast]

I would like to develop my own context ad application similar to Kontera, but I am not a programmer and do not know where to start. All the ones I have seen so far use JavaScript to process the text client side, but they all seem so bulky and add so much to the page size that it seems very limiting since savvy site owners or webmasters will balk at installing this script on even one of their pages let alone the entire site.

I would like a professional opinion as to the best programming language to use for this type of thing. Anyway, I am open to all suggestions and comments from those who love JavaScript AND those who hate it.

Any ideas on how to keep the processing server side? I know the script I use will have to "examine" the text on the page before it can display the ads so I am not sure how to do this server side. Maybe the text for each page could be stored on my server, but that would mean the advertiser would have to provide me with access to their server (I doubt that many site owners would allow this), or at least provide me with the text for the page in question which would complicate the process of updating or making any changes to the text that the client might want to make as well as mess up the entire script if even one word is changed without informing us.

Perhaps the Kontera people have studied this and the resulting client side processing is the ONLY solution? If so, is there a better way to do this than using JavaScript?

All replies will be treated with respect and appreciation.

It's hard to know where to start with this one, except to suggest that if you don't know any programming yet then you have a very steep learning curve. Why not just use Kontera?

Anyway... There is no best programming language; any of them can do the job. I haven't looked into Kontera but I would be very surprised if much of the processing is done client side. It's more efficient to do the work server side. Javascript is most useful as the gateway to AJAX which sends tasks back to the server to process without needing a page refresh. Javascript's main problem is that users can turn it off which then stops your page from working unless you have some other way of producing the same effect.
