    Interpreting that as: user/group/other cannot write

    find . -maxdepth 1 -not -perm /ugo+w

  2. This find will find files that aren't writable by anyone:

    find . ! -perm /222

    EDIT: From hmont's suggestion on the comment:

    find . ! -perm /222 -exec ls -l {} +

    And as Mikey puts on his answer, you can use -maxdepth 1 to limit the find to a single directory.

  3. find . ! -perm /a+w
    find . ! -perm -ug+w

    or some other permutation with symbolic notation to meet your requirements.

    To clarify, the '/' will match any user, group, or other. To match all, precede the mode with '-'.
