It depends what do you mean by GUI: if you're asking if it is a desktop ready release, then no, it doesnt come with GUI, but at any point you can install XFCE/Gnome/KDE on it and turn it into a desktop system. However, you might want to look at PC-BSD which is a FreeBSD based desktop oriented release. If you're asking if it does have graphical installator then yes, it does have ncurses based installator.
