Best Server OS for Someone That Does not Want to Touch a Shell on a Regular Basis?

[Pierre-Luc Drouin]

Hi,

so I have a friend who is looking for the best OS for a web server, that 
allows to configure services (I guess HTTP, PHP, MySQL and web content) 
and do the OS maintenance (OS & package updates, firewall configuration) 
without having to touch a shell. I was wondering if something like 
PC-BSD + CPanel would be the way to go. Would there be other BSD-based 
alternatives? I always do upgrades and configure services through the 
shell and I am not aware too much about the GUI alternatives...

Thanks!
