It'll be a pretty straightforward CRUD front end for a CRM database and commission tracking system. The most complex client side stuff will be the monthly statement generating procedure (which I hope to implement almost entirely within the database, and possibly as a tool external to the web app), and a flexible reporting system. On the client-side there is likely to be much DOM+Javascript manipulation to implement a palatable rich data-entry UI.

The WebKit portion of Webware appeals most to me. Just enough structure and conveniences without losing sight of the basic CGI model. MiddleKit sounds interesting but I'd like to have more control over my DB schema than that might provide. UserKit appears disappointingly underdeveloped.
