Grocery getter

Is there such a thing as a step-through frame that's not err.. feminine?
With a baby seat on the back a traditional frame is a real bitch to mount if
you're not Jean Claude Van Damme. Plus it'd be good to have a bike that the
Mrs could use as a grocery grabber rather than driving the two blocks away
just to get milk/bread etc. I wouldn't mind using it too for such trips, but
I'm way too masculine to be seen dead on a girl's bike. ;-)
She's err... "bicycle challenged" so it has to be dead easy to ride or she
won't ever go near it, so I'm thinking coaster brakes and maybe a 3-speed
hub to be as familiar as possible with the bikes she has ridden in the past.
Anyone selling 3 speed hubs in Oz? I can only find them already fitted to
bikes or the Nexus 7 speeds and they're a bit out of the price range of this
project.
The "Africabike" frame would be perfect if they made them for "rich"
