Finally got it to work! Here's what I ended up with:
--
@owners = Owner.find_by_sql("SELECT * FROM Owners
LEFT JOIN Widgets
ON (Widgets.owner_id = Owners.id)
WHERE Widgets.owner_id IS NULL
")

I noticed that you used a letter to call the table later in the sql
query. Is that a shorthand method or something that I should do to make
it better syntax wise?
Eg. ...
"SELECT * FROM Owners o
LEFT JOIN Widgets w
ON (w.owner_id = o.id)
WHERE w.owner_id IS NULL"
