Something like:

echo \' `cat $data` \'

(if $data were a file)

should get you what you want:  note that ` is a back-tick (often above the 
tab-key) not a single quote

If $data is a variable with some data....

"'$data'"

That is, double-quote single-quote $data single-quote double-quote. So you can 
probably use:

curl -X PUT http://couchdb:port/db -d "'$data'"

if that fails, use the echo trick above and put the result into a new variable 

QUOTED_DATA=`echo "'$data'"`

note the back-ticks around the right-hand statement
