Changing font size of UI element

I'm new to VC - in fact I'm new to Java or anything like it. I'd like to change the font size of the choices I give a user - let's say a radio button list. Is there a way I can edit the source to do this? I read the wiki on changing colors - none of the SAP notes referenced in that thread or the wiki exist. I don't want to change ALL the fonts sizes - just the one for this element. We're on 2004s/SP12 of Netweaver VC.
