After a short search I didn't find much in the way of simple TinyMCE documentation, but I did find a nice guide on using CKeditor:

[docs.fckeditor.net...]

As you can see, the markup from the editor is simply submitted to a post variable. Writing this to a file is a straightforward task if you have a reasonable grasp of php or another scripting language.

Of course, you'd also want to make sure that the edit pages require some sort of authentication.

While the amount of effort required to get this solution up and running wouldn't be too great, if might be just as easy to install a lightweight CMS that could accomplish your goals and more.
