pyExifToolGUI and jExifToolGUI ???

I stumbled upon this:

https://hvdwolf.github​.io/pyExifToolGUI/

and this:

https://github.com/hvd​wolf/jExifToolGUI/rele​ases

Now, I am a bit confused; my take is that these two programs are not associated with plain old ExifToolGUI --- or are they ?

Does anyone know anything about them ?

All three programs you mention seem to be front ends to the command line exiftool. plexiftoolgui is no longer supported and recommends jexiftoolgui which is an open source java based cross platform front end to exiftool. Probably suited to the more computer literate as it not just point and click. Plain old exiftoolgui is a windows thing. Or that's my take on it anyway after having a quick investigate!
