so say if i have xming or another x11 server running on a windows computer, which i plug a flash drive into, is it possible to mount this drive on a remote linux machine? what about if i'm running the x server under linux ?
You will need to share the drive using Windows "file and printer sharing" or some other means. Whether or not you have X11 on the server is irrelevant.
Do you know a good gtkdialog program? Please post a link here
