Ubuntu Server graphical interface?

[Martin Hess]

Serge has pointed out what should probably be a 5th requirement.

* Easy to use

No point in having a GUI that is difficult to use. Windows is full of  
examples of such GUIs and gave GUIs a bad name. Additionally, if the  
tool makes it possible to manage a set of machines at the expense of  
managing 1 machine easily then it has failed the ease of use test.

Here is the requirements list so far:

1) Optional - must not be required for Ubuntu Server
2) Secure - must not have known security issues, must have good known  
security architecture
3) Scalable - must be able to administer sets of machines
4) Open Source
5) Easy to use - for 1 or more machines

Are there any packages that can meet such requirements?
