Comment (by ryandesign):

 Replying to [ticket:59067 kencu]:
 > `zenity` adds a reasonable GUI to `winetricks`, but it comes at the cost
 of some fierce dependencies.

 > I don't mind using `winetricks` in command line mode.

 Do you know what I would need to do to tell winetricks not to use zenity?
