qemu-img is a command line tool, not a gui.  Bloating it with a gui 
dialog box is probably not a wise idea.

Personally, I'm just fine with the current command line behavior:

$ qemu-img
qemu-img: Not enough arguments
Try 'qemu-img --help' for more information

as 'qemu-img --help' tells you how to properly use the command, without 
having to hand-hold you through the process.
