Qtools aims to be a toolkit to support development with CommonQt. This goes to the point of sporting a complete abstraction layer that makes writing Qt applications look like regular Lisp programs. Have a look at the documentation and examples to get an idea.

The project can be found on github including a fully documented symbol index and a getting started tutorial.
As of November 2014, Qtools is on Quicklisp.
