Installing and connecting to Ubuntu KVM guest from a remote Windows 7 Desktop

I have an Ubuntu server 13.04 running KVM
This is a remote server and I want to access it from my work lab/office behind a proxy and be able to install and connect to a desktop OS that I will install as a VM guest. I haven't settled yet but it will be either Linux Mint or Fedora as the guest. I need to be able to install the guest remotely, from the CLI is fine, and I need to be able to connect to the remote desktop with my Windows 7 desktop. So KVM is set up and working and I just want to hear any opinions about what the best method to accomplish this is. I can already establish an SSH session and an OpenVPN connection to it so connectivity is fine. I just don't know how to properly utilize KVM from a Windows 7 desktop in order to install and use the guest OSs. Thanks!
