There is no free GUI package available on sourceware.cygnus.com yet.

X is not appropriate for most embedded systems, it is just too big.
Also, a typical X installation involves at least two processes, the
server and the client, which does not map well on to eCos. There are
other graphics libraries, e.g. NanoGUI
(http://www.linuxhacker.org/nanogui/), which might be more
appropriate. An important issue here is the kind of display you are
targetting - TV, large LCD, small LCD, ... - since something suitable
for a small LCD might look rather poor on a larger display.

So far there has not been a contributed port of NanoGUI or anything
similar, and none of the customers paying Red Hat for a supported eCos
port have specified a GUI library as a requirement.
