Yes it has GUI. Flutter is the main/official way to build apps on it. The OS shell is also written in Flutter if I remember correctly. So far, the OS has been seen on or confirmed to release in near future on one Google Home device. Technically though, it seems to be designed for all kind of consumer devices ranging from phones to desktops.
IMO this is more or less an experiment which if successful, will end up merging/replacing Android and Chrome OS into a single OS. Android and Chrome runtimes can be ported to Fuschia and the underlying OS can be swapped on many devices. New devices can ship with Fuschia + an android compatibility layer. Developers would be able to ship native Fuschia or android apps. Would work on phones, IoT, Chromebooks and could be install-able on desktops.
This is all just speculation though and a lot of things need to go right for this to happen but I'd imagine this would be the ideal/desired outcome for its creators.
