.. but I only have a dial-up running windoze!

You can get the benefits of working on a GUI from a windoze 
dial-up!  Do the following:

1)Download and install DEV-C++ 4.9.9.2 (or higher).  Run 
DEV-C++ and elect all the "OKs" and "Nexts" you can.  It
will take a while the first time for all of the necessary
stuff to be created. (http://www.bloodshed.net/dev/devcpp.html)

2)Download and install the SSH.ORG free windoze ssh client.  
(http://www.ssh.com/support/downloads/secureshellwks/non-commercial.html)

3)To start editing a new ".cpp" file, use DEV-C++ to create a 
new file and save it.  Upload this file to a UCS Solaris Unix 
host with the SSH FTP client.  Double click on the file in the
UCS Solaris Unix host file list on the right side of the SSH 
FTP client.  The file will open in DEV-C++.  When you want to save 
it, either exit DEV-C++ or save locally. You will be prompted 
for permission to upload the file to the UCS Solaris Unix Host.
Note:  You may have to minimize the Dev editor to see the
premission dialog box.  To run, log on to a UCS Solaris Unix 
host via the SSH Telnet client and use your compiler as normal.

4)To edit a ".cpp" file that exists on UCS, connect to a UCS 
Solaris Unix host with the SSH FTP client.  Double click on 
the file in the UCS Solaris Unix host file list on the right 
side of the SSH FTP client.  The file will open in DEV-C++.  
Running and saving is as in step #3.
