I'm not familiar with GPT, too. I got to know it at FrOSCon 2010 at the
FreeBSD booth. Nevertheless it looked quite interesting and is
necessary for partitions bigger than 2 TB.

I don't know its usability, but there's a CLI tool for GPT:
gdisk resp. GPT fdisk

It's already in [extra] and on the LiveCDs Parted Magic
(http://partedmagic.com) and SystemRescueCD (http://www.sysresccd.org).

Parted has no ncurses GUI but can be used from the command line.

I'll search for GPT tools again later.
