We are assuming you have a ks0108 type display.
Is that the case?
If so you can also download the latest glcd v3 library and look over the included documentation.
It is quite complete, in both pdf and searchable/linkable html formats:http://code.google.com/p/glcd-arduino/downloads/list
And has diagrams of how to wire up the panel so that it will work with
One word of caution. Make sure you have an accurate datasheet and make sure
you don't just try to hook things up using any sort of "trial and error" method
as incorrectly connecting wires can burn up the glcd or the Arduino board.
If you aren't sure about the wiring, just ask questions, and folks will readily help out.
Also, if you find that you want/need to use a ks0108 glcd and still need additional pins
for other devices that the UNO can't supply, have a look at the Teensy boards:http://www.pjrc.com/teensy/
IMHO, they are by far the most cost effective way to get more resources for arduino
projects if you are not needing to use an arduino shield.
The Teensy boards have more of just about everything, pins, RAM, FLASH, eeprom and even
support USB natively. The native USB allows many interesting applications that are not
possible with most other Arduino type boards.
The glcd v3 library also supports Teensy "out of the box" as well.
