I am using ubuntu locally. Also I have another server running windows 7. I want to start firefox or notepad on windows 7 through the bash on ubuntu. And what I want is to let the firefox/notepad windows displayed on windows 7 like I started them locally on windows 7. I have SSH configured on windows 7.
The best advice I can give you in this is try using a VNC Server, they can be used on Windows or Linux systems and the clients are also available for linux.
I suggest looking up tightVNC http://www.tightvnc.com/
