Need Help for A Very Special Friend

I want to [quickly] build a website for a fellow Realtor who lost her battle with cancer yesterday. My goal is to have a community place where anyone can go to the site, sign a Guest Book with their thoughts, post photos, and interact in a Facebook kind of way (but not use facebook).

Can anyone point me in the direction of a website provider who offers Guest book and photo upload possiblilities (for guests in addition to the webmaster) with an easy to use, WYSIWYG interface as I am not a web programmer. I would really appreciate it.

I also want to incorporate a PayPal function where people can make donations in the name of the trust set up for her children.

Thanks so much for any help anyone can provide.
