Dragonball Z Gt doesn't exist, but Dragonball GT is it's own series...
There isn't one that is part of the official release.
The GT series, if you , mean dragonball, it was the second sequel to dragonball, GT means 'Grand Tour' as the main characters (Goku, Pan and Trunks) go on a few big adventures or grand tours. Good series.
