where did you get Wine? if your running normal Wine in OSX you will always have terminal output because you have to run it through terminal. you can set virtual desktops in winecfg (wine winecfg). Xquartz is X11 for Mac OS X. Get the latest releases at http://xquartz.macosforge.org/ If your using some 3rd party program (http://wiki.winehq.org/ThirdPartyApplications), its not really supported here, as people are probably not familiar enough with the specific program to know the differences in normal Wine and the 3rd party app.
