Hi, Plodfather.
Yep, those 0-30mins beginners' schedules work. Took me ten weeks (I repeated a couple of weeks when I struggled a bit) and the first time I ran non-stop for 30 mins was a wonderful feeling. Can now tackle 10k runs (slowly!) and have recently joined my local running club (plodders' section).
There's no secret or mystique about it ... but you MUST stick to the schedule. I really did follow it to the letter. Motivation tends to come and go and I sometimes had to force myself out for a plod. But if you really want to succeed, you'll do it.
Hope this helps. Let us know how you get on.
