This tasty dish was given by K.os in a discussion regarding "food and arcade games" on the alt.games.mame newsgroup some years back. For 3) I normally just use 3 cups of hot water and 4 maggie stock cubes. Here's what K.os wrote:
An easy, healthy and tasty recipe, which requires little preparation and is
done in about 1 hour of baking.
0) Pre-heat the oven to 190 C
1) Take 3-5 Chicken thighs and remove the skin and fat. Season with salt
and pepper, chili pepper powder, and a bit of basil.
2) Cut up some mushrooms, zucchinis, onions, garlic.
3) In an oven dish (pyrex is nice), mix the cut-up veggies, a cup of pearl
barley, three cups of broth (you can use canned concentrated broth, in
which case just put in the can of concentrate and one can of water), a
tablespoon of balsamic vinegar (or wine vinegar if you don't have
balsamic), and 2 tablespoons of butter.
4) Mix the veggies, barley, vinegar and butter, season with salt, pepper,
chilli pepper powder and herbs.
5) Put the chicken thighs on top of the veggie/barley mixture, and put it
all in the oven.
6) Bake at 190 C for about 1 hour. After 1 hour, remove the chicken and check
the barley. If there still is a lot of broth, give it a stir and put it
back (with the chicken on top) for about 10-20 mins and check again.
7) Serve the chicken with a nice pile of barley with veggies, and a good
beer. I recommend McAuslan St-Ambroise Ale, but it might not be available
everywhere.

You can also buy Pearl Barley in the Supermarkets (Coles or Woolies.)

yeah, not quite the same bizier 
Pearl barley is dehusked and polished.. you'd probably find it with the "soup mix" sort of things - you know, split peas, lentils, etc.
