no, the LAMP-stack does not have a GUI.
LAMP is an acronym for:
Linux: the OS-kernel
- usually there is no GUI for administering the kernel of your system
Apache: a web-server
- simply put: no, afaik there is no GUI to administer apache
phpmyadmin to administer this service, but it requires
php to be configured correctly
- simply put: no, afaik there is no GUI to administer apache/php
most administrative GUIs for administering servers are web-based GUIs: this means that you need to have a web-service running (apache), with programming capabilities (php), both running on the system (linux). you obviously have to have these systems up and running in order to build upon them.
to conclude: LAMP is about server administration. servers in unix-world usually do not have without a nice GUI to configure everything. instead the user is supposed to configure their system on from the cmdline.
the best you can get to get you started, is probably a book on LAMP, to learn the basics (check o'reilly).
