177 is needed if you want to run xdm on the host side which needs to
be configured properly to allow remote X servers to be managed. Since
you are using cygwin/X11 (I guess) you would not really need your
display to be managed by your AIX machine.

Your AIX machine needs to be able to connect *to* your XP workstation
on port 6000, not the other way round. You should be able to
telnet to your X11 server to test the connection, e.g.:

$ telnet 192.168.10.58 6000
Trying 192.168.10.58...
Connected to 192.168.10.58.
Escape character is '^]'.
...........
Connection closed by foreign host.

I do not speak X11 protocol well enough to get anything meaningful
from that telnet session, but the important part is that the connection was established and closed by the X11 server on the XP workstation.

You also need to check xhost settings on the XP machine to allow
X11 apps from your AIX machine to actually talk with your X11
server on the XP machine...

need to have the port 7100 opened. Is this true ?

Only if you want to run an X11 font server on your AIX machine to
serve fonts to your clients. A cygwin/X11 installation comes with
a lot of fonts, so this may not be necessary.

I can not use SSH because the SSH is not either installed on the AIX
server or not setup to accept connection (We don't want to use SSH). Is
SSH the only way to connect to AIX from XP over a firewall ?. What do I
have to do to get this connection working ?

ssh makes X11 easier because it you need only one tcp connection that
originates on the XP side and ends on the AIX side. The ssh server
can be asked to set up the display environment on the AIX side to
tunnel X11 traffic back to your XP machine on that established ssh
connection.

I have installed the full version of Cygwin.

Congratulations! A full install of a current version of cygwin/x11 can
be quite tricky.
