updating single page of website

[Dust]

Hi all

Newbie here so, please be gentle..

I've got a website that I built for a client who's a local musician. It uses a really simple XML file to generate the gig listing page and I'm looking to build a simple CMS solution to update it so I can hand the site updates over to him and not have to update the XML file manually.

Is GetSimple what I'm looking for to let me do this? I have to say, I'm completely lost at the moment and not really sure where to start so, if I'm getting the wrong idea of what GetSimple is about, now is the time to tell me...

cheers
