GUI Installation of Server

I currently have two MS Windows 2003 Servers running and I'd like to add a Ubuntu server to the mix so that I can learn a bit about Linux, php and MySQL.While I realize that most Linux servers are command line only, I would like to install a GUI front end because I simply don't have time right now to become familiar with the command line.I just installed the latest Ubuntu server but there was no option to install the GUI.After trying a few things I've read, I got the GUI working but apparently I'm missing a lot of GUI apps. So, I'd like to do a fresh install and include the GUI so that I'm certain that I have all of the pieces.Is there a straight forward way to do that?Thanks,Mac
