You don't say which version of Windows you're using. With Vista and Windows 7, "Disk Management" will let you "Shrink Volume" to reduce the size of C drive and create Unallocated Space. The Unallocated Space can then be Partitioned and Formatted to create another drive.
In general with Partitioning software, it will run a wizard to create the new drive and let you select from where to take the space required. You would then specify that you wanted to create a 60GB drive taking the space from your existing C drive.
The *existing* Unallocated Space of 9.6GB could be a Recovery Partition to restore the PC to factory default settings, so I'd suggest you don't interfere with that.
