someone talked about integrating one via the html module plugins.
I assume that at this time there is no option for allowing people not familiar with HTML to post content.
The html module is a basic service for general content. You could make a set of pages you could navigate through, but it would be extremely tedious and not really suitable for a non-techie, even if there was a wysiwyg editor.
The modules provide more structure for editing content types and navigation in that content.
Nukes does not provide a full CMS system, with editing templates, workflow etc - see OpenCMS for an example of what that would look like.
