Actually yes, PuTTY is capable of forwarding X11(The standard UNIX window server) from the remote host to your machine, though there's a few steps in the process.

1) Install an X server on your Windows machine. There's many Windows implementations available, lots of them commercial, some open source(cygwin has one I believe).

2) Tell PuTTY to forward X11 back to your computer when you connect. That's under connection -> ssh -> X11. Now when the remote host connects to 127.0.0.1:????, it will actually connect to a socket made by sshd, which will obligingly forward the connection back to your ssh client, which will connect to the local X11 server you configured it to. (You may need to set X11Forwarding to "yes" in /etc/ssh/sshd_config on the remote host, then restart sshd.)

3) Make sure DISPLAY is exported to the appropriate address on the Linux machine(sshd will probably set it itself, but it's good to check).

4) Run the graphical Linux command on the remote terminal.

5) It should pop up on your screen.

xon

xon(1X) 																   xon(1X)

NAME

       xon - start an X program on a remote machine

SYNOPSIS

       xon remote-host [-access] [-debug] [-name window-name] [-nols] [-screen screen-no] [-user user-name] [command...]

OPTIONS

       Note  that  the options follow the remote host name (as they do with rlogin).  Runs xhost locally to add the remote host to the host access
       list in the X server.  This will not work unless xhost is given permission to modify the access list.  Normally, xon disconnects the remote
       process	from  stdin,  stdout  and  stderr to eliminate the daemon processes which usually connect them across the network.  Specifying the
       -debug option leaves them connected so that error messages from the remote execution are sent back to the originating host.  This specifies
       a  different  application  name	and window title for the default command (xterm).  Normally xon passes the -ls option to the remote xterm;
       this option suspends that behaviour.  This changes the screen number of the DISPLAY variable passed to the remote command.  By default, xon
       simply  uses  rsh/remsh/rcmd  to  connect to the remote machine using the same user name as on the local machine.  This option cause xon to
       specify an alternative user name.  This will not work unless you have authorization to access the remote account, by placing an appropriate
       entry in the remote users file.

DESCRIPTION

       The  xon  program  runs the specified command (default xterm -ls) on the remote machine using rsh, remsh, or rcmd.  xon passes the DISPLAY,
       XAUTHORITY and XUSERFILESEARCHPATH environment variables to the remote command.

       When no command is specified, xon runs 'xterm -ls'.  It additionally specifies the application name to be 'xterm-remote-host' and the  win-
       dow title to be 'remote-host'.

       xon can only work when the remote host will allow you to log in without a password, by having an entry in the file permitting access.

BUGS

       xon can get easily confused when the remote-host, user-name or various environment variable values contain white space.

       xon has no way to send the appropriate X authorization information to the remote host.
