I think gparted should be able to do this for you, first move the
start of the linux partition and filesystem towards the end of the
disc (you'll have to shrink that filesystem, also done in gparted) and
then move it to create free space next to windows. Moving the start of
a filesystem is more risky than simply shrinking or growing it and
could take a while, you definitely want to have a backup. I'd opt to
use windows tools to do the ntfs growing afterwards (since it's
windows's filesystem). If your linux /boot is on sda3 you may need to
reinstall grub after the move too, so make sure you know how to do
that.
