$n!pR, of PS3Hax, has released a Windows GUI for Geohot's tools. The app currently assists in SELF signing and PKG signing. $n!pR also plans to possibly incorporate unself.exe and other tools in the near future.
DownloadThis is my GUI for the signing tools from geohot. I might expand them to include unself.exe and other tools later. Tested working with the one app I made so hopefully it works just as good for anyone else who wants to try it.
This is a more improved version from the one I posted earlier.
