No, it sounds like this user wants full-on VDI or SAN booting - diskless workstations and a machine on the back end to host the Windows install.
This is possible, but it requires at least 2 machines - one to boot from, and one to serve or run the install of Windows. There's no way around that. After that, there are free ways to implement VDI, but they're not for the faint of heart. These are the reasons why most people choose to use Microsoft or Citrix VDI solutions - time is also money, and it takes a good deal of time to implement the "free" solutions, making them no longer free . If it's just for you, and your time will be spent on learning, spending your time on learning can be worth it though.
Note that these can either be VDI solutions (connecting to a Windows 7 image *hosted* on a virtual server), or iSCSI boot from SAN solutions. Both are worth learning if you have the time, but the VDI solution is going to require commercial software. If you're stuck in broke-land at the moment, learn iSCSI booting instead:
