with:
someone    dude-user=(ALL) NOPASSWD:ALL

you are saying that user someone may run on dude-user computer ALL
commands without having to type a password
Not sure what the (ALL) - the only as operator) does here.

But you are tring to run the command as the user dude-user (not as
someone, using sudo -u)
$ gksu -u dude-user wine "/home/dude-user/.wine/drive_c/Program
Files/Dude/dude.exe"

Try
someone    ALL=(dude-user) NOPASSWD:ALL

If that works you may then replace someone with a group, say
dude-users groups and replace it with
%dude-users    ALL=(dude-user) NOPASSWD:ALL

And, either way, replace the first all with your computer name,
and replace the last ALL with the command
%dude-users    ALL=(dude-user) NOPASSWD:wine
"/home/dude-user/.wine/drive_c/Program Files/Dude/dude.exe"

I didn't try any of it, but hope it may get you going a bit further

see man sudoers

Luis

PS: It may be simpler to set
%dude-users    ALL=NOPASSWD:wine
"/home/dude-user/.wine/drive_c/Program Files/Dude/dude.exe"

and run as someone (that belongs to the group dude-users) just
$ gksu wine "/home/dude-user/.wine/drive_c/Program Files/Dude/dude.exe"

Again, hope it helps
