Sorry to hear that Leemond. From personal experience, your friend's widow will need plenty of practical support.
Of course this all depends on how well you know her, how close you live to her and how much time you have on your hands. Make sure she has your mobile number and make it clear she can call at any time. Offer to take your godson out for a while so she can have some time to herself. Let her know that you will help out with some of the bloke's jobs if she needs it (getting car MOT, DIY, Gardening, fixing computer etc.).
When my wife died this year, loads of people said "call any time", but the ones that have helped the most are the ones that have phoned me up and said "let me help".
