Sorry that it took a while, but I got largely distracted by other things. Finally the Windows installer binary for [guitone 1.0rc5](http://www.thomaskeller.biz/blog/2010/11/06/guitone-1-0rc5-released/) is [available for download](http://guitone.thomaskeller.biz/g/download) – compiled under WinXP SP3 with Qt 4.7.1.
Please let me know if you encounter problems, for example by reporting issues in [guitone’s bug tracker](https://code.monotone.ca/p/guitone/issues/).
