It was quite common to run QNX on desktops as a development host for embedded systems AFAIK. GUIs for QNX predate the Amiga deal, and have existed since the late 80s. The original was QNX Windows, which was either a reimplementation or port (not quite sure which) of Open Look on a custom non-X11 window server, running on later versions of 2.x and all versions of 4.x. Later versions of 4.x added Photon 1, which looks like a cross between Motif and Windows 9x, again based on a custom window server (this time with a rather unconventional multi-process architecture). The 90s-era demo disk was based on 4.25 and Photon 1 (there was also a 2.x demo disk back in the 80s but this didn't have a GUI). 6.0 came with Photon 2, which is still Win9x-ish in terms of organization and is a fairly straightforward evolution of Photon 1, although the widgets look very vaguely Amiga-like in 6.0-6.2. 6.0 came out slightly after the Amiga deal, so that might be the reason for the Amiga-like theming. Neutrino was not the name of a GUI, but rather of the entire OS that succeeded QNX 4 (the first versions of Neutrino used Photon 1 but were incapable of self-hosting and were developed alongside 4.x; 6.0 was the first mainline QNX version to be Neutrino-based). There were also the i-Opener (running 4.25) and Audrey (running 6.0) internet appliances of the late 90s.
