I've got a program that we use here at uni that i'd like digitally signed so that when students run it, they see the name of our college displayed, rather than just "unknown publisher"

I've had a search around for how to do this and it seems like I need to include a .pfx file

http://www.chilkatsoft.com/p/p_218.asp

that link gives details on how to do it once I have the pfx file.......but I'm not sure how to get a pfx file

Is it something I can create...or something that needs buying?

You can create your own self signed certificates with OpenSSL, however if I recall correctly, the certificate authority's certificate needs to be inserted in to the computer's root store in order for it to work correctly.

Alternatively, you can buy a certificate from a well know company such as VeriSign.  The VeriSign certificate authority should already be part of windows. 
Information about VeriSign code signing certificates can be found here: http://www.verisign.com/products-services/securit...ices/code-signing/

Edit: Here is a step by step guide for creating your own signing certificates: http://www.top20toolbar.com/misc/codesigncert.htm
