If you want to go there straight after your wedding I would say very difficult.
My wife applied for a Schengen visa through an Italian consulate last month and it took two weeks to issue the visa.
You could try to apply for a visa before you get married, but you may have difficulty doing that as your fiancee may not be able to provide enough documentation to the Embassy. It is much easy to apply for a Schengen visa once you are married.
