If this question comes just out of curiosity, then we will say
NO it is not possible, but if you don`t want a
clustered index on it, then yes, we can create a Primary Key with Non Clustered Index. See the below link
http://www.dotnetfunda.com/forums/show/22466/how-to-create-a-primary-key-without-clustered-index Keys are used in the queries (Where, Join, Group By, Order By etc), and index on the keys make them more faster than non key columns, so its a better choice to have an Index on keys, As far as I am aware all popular relational databases uses indexes on the Keys.
Probably in the old version of SQL Server we can do that, but not on the SQL Server 2000 and above version.
There would a very rare example where a user genuinely wants only constraint without any index.
