Actually, one can exist without the other.

If user A has write permissions on the DIRECTORY containing file B, but not on the file itself, then the user can DELETE the file but not modify it.

OTOH, if user A does NOT have write permission to the directory, then they CANNOT delete (nor create) files in the directory. All you have to do is make sure there is a null-length file already in the directory, and the user will be able to read/write it (provided it has the right permissions) but NOT delete it.
