'Stone Base' is a free go-database/record editor/viewer/GnuGo interface for Windows. It used to have a website at http://stonebase.bcyvr.com/bbs/.
Blurb from the homepage: "StoneBase is a FREE multiple-function software designed for supporting GO study. The software is planned to be developed as an integrated platform with game record (kifu) management, record playback, record edit, GO skill learning, playing GO on LAN / IGS, playing against AI (GNU GO) and other more useful functions."

To download, search for the big red link saying 本地下载, there are 5 of them, the first one worked fine. It's a 180mb .rar file containing different files:
弈典(安装版): an automated setup executable
弈典(绿色版): another zip containing a skin builder and the actual stonebase software. (just copy/paste no setup needed)
棋谱库: a game database
Before you run the software for the first time, open StoneBase.ini and change the first line Language=chs.ini to Language=eng.ini
