How about PartEd live, it is a Linux liveCD (Debian based) that contains
a GUI for GNU parted and all the available Libre command line file
system tools, including built in knowledge of how to invoke them for
common tasks like the OP needs.  It doesn't however include qemu-img
or qemu-nbd to manipulate disk image files.  While these can be
installed to the liveCD RAM disk from Debian repositories, the
PartEd GUI doesn't know how to invoke them on-the-fly.

For XP disks, PartEd GUI knows about ntfsresize and some unspecified
tool for (V)FAT filesystems.

Most Linux-based tools can work directly with raw images, either
directly or via the "loop" device as configured with losetup
