Having built Tomoe for Debian I was ready to go to develop a nice widget implementing the basic features of Tomoe giving you the TomoeHandwritingWidget.

The widget allows for drawing with the mouse and shows a typical character grid to assist the input. Included is a demo application that is fully usable do to handwriting recognition for Chinese characters. The widget is released under the LGPL (license of Tomoe and future license of Qt), remember though that PyQt is currently GPL only.
