Sorry, I do not know of any programs whereby you can obtain a British work visa unless you are a student. I do believe that there is a 3 month grace period for BUNAC; so, if you graduated from university within 3 months (say, a winter graduation), then you may still qualify.
Otherwise, you're going to have a really hard time getting a job in the UK. My understanding is that the "easiest" way to do so is if a British company hires you and sponsors your work visa. However,
a) you have to convince the company to hire you and not a British citizen or European Union (EU) citizen.
b) the company has to convince the British immigration folks that they just
had to hire you and not a British or EU citizen.
c) you must be in the USA at the time the work visa is issued.
That won't be easy unless you're a special kind of engineer, researcher or something like that. If you just want to be a secretary, then it's kinda hard to convince people that American secretaries are just soooo better than British ones.
Here are three things which may help you:
1) Check out the British Home Office website for information on immigration policies and procedures.
www.homeoffice.gov.uk
2) You may be able to obtain a job through one of the British companies which aim to specifically hire young, college-age people. There is one website I know which advertises all kinds of odd jobs, including LOADS of positions for summer camp counsellors, life guards and activities teachers for kids. It never hurts to look.

3) Finally, there have been loads of threads on GC where people have asked about work visas, study abroad, and travel to the United Kingodm. You may want to try a search for "England", "London", "Britain" and so on.
Good luck!
