First you need to know which OPC you want to use.

• "Classical OPC" DA/HDA and A&E based on Windows COM/DCOM
• OPC XML/DA, DA as a web service but with some limited perfomance.
• OPC UA, the last specification allowing you to implement it on non Windows platform and merging DA, HDA and A&E.

After that, you could choose the language you want to use and so use some SDK free or not.

One good website for OPC : http://www.opcconnect.com/source.php has lists of Toolkits you could use.
