No pure Javascript version?

I think I am in over my head on this. I am a VFP developer, been using FCKEditor (and CKEditor) for many years but now want to integrate CKFinder. (Yeah, I know VFP is no longer supported and why would anyone want to develop anything in it anyway, but that's a long story),

I use javascript for a lot of things (including jquery and add-ins) but not ASP or PHP. I don't see a pure javascript version of CKFinder, so it looks like I can't use CKFinder without having something more than I have now, so the easiest I think is going to be adding PHP.

But all I want to use it for is supporting CKFinder and the installation instructions are quite extensive and are aimed at being able to develop everything in PHP (which might be a good thing in the long run, but I have to get CKFinder working soon) and don't want to mess up the web server installation I have now.

So, am I right in thinking there is no way to use CKFinder without PHP or ASP (i.e. with just javascript)?
If I have to add something to my development library (and eventually redevelop everything), is PHP the recommended way to go?
And if PHP is it, can anyone guide me in understanding what I need to do to get PHP installed and CKFinder working as quickly as possible.

Thanks very much,
