FCKeditor can be made to use pretty much any back-end language.

There are quite a few other similar Javascript-based editors. The back-end need only know how to store/retrieve/list the stored articles.

For those that downvoted this, it's absolutely clear that a plain HTML-based user interface cannot do what punch_card_don has asked for.

He asks for the solution to:

• looks/works like MS-Word or Dreamweaver
• paste in a picture, etc.

I hope you realise that this can't be done without extra client-side support.
