As far as I know, you only need a certificate with has sign purpose. You can import it in the certificates store of Windows to use it directly.

After that, you can use it to sign using one of the many libraries available. For example:

• In Java, the signature applet created by the Jaume I University (CryptoApplet), that you can find at projectestic.uji.es/pr/cryptoapplet
• In .NET: a new project I'm involved in (XAdES .NET Project), that you can find at xadesnet.codeplex.com
