Is there a way to allow certain numbers to be called from a locked phone?

When I got my first cell phone I was told to put a "In case of an emergency call XXX" at the top of my list of phone numbers. While I haven't ever benefited directly from that, I have benefited from similar emergency preparedness advice. My old phone finally made the trip to electronics heaven (RIP dear RAZR) and I moved over to a Verizon Android phone (Samsung Stratosphere - with Gingerbread 2.3.5). I really like that I can "lock" this phone to prevent someone else from using it in malicious ways, but I would really like a method for someone to be able to determine who my emergency contacts are, and ideally contact those people, if I'm ever incapacitated. When I saw the "Emergency Call" button I thought that might be the functionality I was looking for, but it isn't - ( https://android.stackexchange.com/questions/7731/what-is-an-emergency-call-and-can-i-set-number-for-it ) Is there any way to have two or three people and their contact info accessible without unlocking the phone? ***Clarifying edit***: Maybe I'm being picky, but I'd also like to have my emergency contacts actually able to be contacted, i.e., someone could pick up my phone - without knowing the lock code - and actually be able to *call* my emergency contacts.
