Simple Front and back end CMS

Basically I am looking for 2 apps/scripts:

1. A text(html maybe) loader for flash, that loads an external text file and displays it.
2. A WYSWYG text editor to load that text file for editing. Basically a small CMS (not necessarily in Flash, php will do fine as well).

I am not looking for a complete online CMS suite, just something I can integrate in to my flash program I am already working on.

I found several tools but nothing that was really compatible with each other.

Would be great if someone could help.
