GUI over a 28k dialup?  ouch.      there's no network connection at this 
remote site?   its going to be really really slow over dialup.  I'm 
talking minutes to paint a screen at 2-3kbyte/sec serial speeds (a 
1280x1024 24bit desktop is 3.6 million bytes).     use a really simple 
theme on the desktop with no shaded borders, no backgroun graphics 
('wallpaper'), etc.    Sending a single full screen 1280x1024 
photographic image could take a half hour or more.

FreeNX is probably your best bet.   i've never set it up, so you'll need 
to find someone elses HOWTO ...    NX protocol runs over TCP/IP 
networking, so you'll be setting up your modem (I still recommend a 
serial modem) to answer a PPP dialinn TCP session, which you'll connect 
to with a PPP dialup session much as we did for the internet in the days 
before broadband.

linux can be completely managed via shell.   NONE of the dozens of unix 
servers I manage have any sort of console screen attached to them.
