There's also KLone (http://www.koanlogic.com/klone/): "KLone is a fully-featured, multiplatform, web application development framework, targeted especially for embedded systems and appliances." It uses C/C++, and can be used with either the GPL or a royalty-free commercial license.
1.) It's a cool hack (if you like C++)
2.) It's pretty useful if you develop for an embedded environment (embedded webservers etc.) and need to avoid GPL'd code
