(first I want to say I just found this and I am not the programmer of this GUI) 

Unfortunately it seems all GUI's are being named "MyDefragGUI"  so there may possibly be some confusion

Anyway, the link is http://www.mydefrag.net/ and they also have a Gui For JKDefrag (I had one, but it was a different Interface all together for JKDefrag .. both of those GUIs seem really good)

I am currently downloading the new MyDefragGUI from that site and will see how well it works with the latest version of MyDefrag
