As mentioned in my F14 Dual Boot Options page, gparted and qtparted are graphical programs that can be used to create and delete partitions in Linux. Although I rarely use them, since I still prefer PartitionMagic due to its ability to re-size and move Windows, DOS, and (sometimes) Linux partitions, I feel that they are important enough applications that they warrant a separate installation page, however small. To install the applications, use yum:
~> sudo yum install gparted qtpartedPress 'y' when prompted to install the programs and any additional dependencies. Either program can now be launched from the command prompt.
