You can do this with intercalate from Data.List

 showList :: Show a => [a] -> String
 showList = intercalate ", " . map show

The map show converts each element to it's string representation with quotes (and any internal quotes properly escaped), while intercalate ", " inserts commas and spaces between the pieces and glues them together.
