Apache is configured thru text configuration files. This has advantages and disadvantages. Management can be done from any computer that has internet access via ssh. Editing a configuration file by hand implies a learning curve. There are open source graphical tools that make this task easier:
Comanche: It is crossplatform and runs on Unix/Linux, Windows and Mac. Check the website for screenshots and in-depth information. Disclaimer: I am the main author of Comanche, so remember, there are no bugs, only undocumented features :)
