Hmm, whilst I imagine that someone could create an extension for this I wonder what would be gained by it.
This looks to me just to be one of those "fluffy GUIs" on top of QEMU, which probably has ten (to twenty) times the size requirements as the underlying tool. Well, given the fact that (according to the web page) it's last release was more then 3 years ago, I furthermore wonder whether it's (fully) usable with the QEMU versions in the repository, as QEMU has the habit of changing it's parameter around from version to version.
If you want to have a go with a (QT) GUI controlling a VM I'd recommed 'VirtualBox' (which is in the repository).
