partitioning - Can I change file systems inside of partitions within GParted?

I'm looking to share documents, pictures, etc. between Windows 7 and Ubuntu 12.04.1. I have an extended primary partition (sda4) that is comprised of a swap partition (sda5) and a "/home" mount point storage partition (sda6). This sda6 storage partition is a ext4 file system. As I understand it, in order for Windows 7 to recognize the data, this storage partition needs to be an NTFS format. Can this ext4 format (sda6) be changed to NTFS using the GParted Partition Editor? If not, is there another way to make this happen? Thanks so much in advance.
