grub configuration tool

[Marvin GodfatherofSoul Bellamy]

I just installed RedHat 7.3 with GRUB as my boot loader.  Problem is I 
didn't know how to configure GRUB, so I just replaced it with LILO. 
 Does anyone know of a GRUB configuration GUI tool?  Is there any 
significant differences between the two?  This is just a test box, so 
"working" is my only requirement, but it'd be good to know for future 
reference.
