I'm sure this is not the slick answer you're probably looking for,
but I've set up several church websites using XWD and had a page link to a blog I'd created for the purpose. Inside the blog you can give him editing rights (along with yourself) and he can upload text, pix, sounds etc. It's a simple fix that doesn't cost anything. You can put a header on the blog that matches his (your) website.
Worked many times for me...
