Michael, I'll do this piecewise.
My X2Go client rev is 4.0.3.0
I have not yet downloaded the debug rev you cite below - will do that next.
Installed Putty (full installer). Following your directions, I hit Open and
then answer No to caching the key (just try once).
The result is a DOS-like window with these 2 lines:
Unable to use key file "C:\Cyclops\data\id_dsa" (OpenSSH SSH-2 private key)
login as:
Just for the hell of it, I did enter the username at that prompt. But then it
asks for a password, which of course I don't have - there is none, which is the
whole point of this exercise.

1st, FYI, You do need "Try auto login" disabled when using an SSH key
file on the Windows client.
2nd, What version of X2Go Client for Windows are you using? If you are
using the latest version (4.0.3.1-20141214), you can use a debug
build. If you can copy the entire command-line output from the debug
build, great. (A command-line window opens when you launch the debug
build.) Otherwise, at least tell us the last few/several lines before
it fails to connect.
Note that you need to either launch the debug build from the start
menu / desktop shortcut, or from the command-line with the "--debug"
argument passed.
Latest debug build:
http://code.x2go.org/releases/binary-win32/x2goclient/releases/4.0.3.1-20141214/non-default-builds/x2goclient-4.0.3.1-20141214-debug-setup.exe
3rd, in addition to #2, please try using PuTTY (Windows SSH client) to
connect to the machine. You'll need PuTTYgen too.
Full installer:
http://the.earth.li/~sgtatham/putty/latest/x86/putty-0.63-installer.exe
Individual binaries you can just download & run (currently 0.63):
http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe
http://the.earth.li/~sgtatham/putty/latest/x86/puttygen.exe
Launch PuTTYgen and import the SSH key by going to: Conversions ->
Import Key -> select your private key file.
Then "Save Private Key".
Then when you launch PuTTY:
specify the hostname/IP
Specify the port (if you never changed the port, 22 is the default).
Then: Connection -> SSH -> Auth -> specify the "Private key file for
authentication"
Go back to "Session".
For convenience, give the session a name and click "Save".
Now click "Open" (to connect.) If you get an error message, please
tell us what the error message is. If not, enter your username on the
server. (If you get an error message after you enter your username on
the server, please tell us what the error message is.)

No joy yet.
I generated keys on the linux side:
ssh-keygen -t dsa
Copied the public key to "authorized_keys" in ~/.ssh
Copied the private key by sneaker-net to the Windows machine.
There, I specified the latter (key file) in the field "Use RSA/DSA key for
ssh connection".
Then tried connecting - can't do it (tries quite a while, then times out).
I did try both with and without the box "Try auto login" checked; doesn't
work either way.
Left the last 2 boxes unchecked.

OK, indeed it will not work without authentication.
Would like to try the public/private key route. I've done this for
ssh agents between linux machines, using ssh-keygen to obtain the
keys. Not clear how to do so w/X2GO client running under Windows.
Can you provide some instructions?
If you have access to a Linux machine, just run ssh-keygen there with
the usual parameters, copy the private key file over to the Windows
machine, and specify it in the session settings (there's a field where
you can specify the path to an RSA/DSA key). On the Linux box, add
the public key to the authorized_keys file of the user account you're
trying to log in as, and you should be all set.
If you want to create your key pair on Windows, you will need to use
either ssh-keygen from a cygwin install, or PuttyGen.exe from the
PuTTY tool suite - for the latter, you will need to use the "export"
function of PuttyGen's GUI to save the private key, as PuTTY's own
*.ppk key storage files are incompatible with standard ssh.
