How can I make a potted herb mini-garden?

I don't think they gave you all the facts about growing herbs; especially indoors. Most of the ones you mentioned are grown from seed (in the spring) so they can be planted outdoors where there is plenty of sunshine for them to mature and produce their own seed in time. Success with indoor herb growing would depend on the space available, sunshine or grow-light available. Gardening with the maximum amount of needed elements is tricky enough, indoor gardening is expensive, and you need lots of space to set pots of soil under grow-lights or in very sunny windows . Winter temps usually require removing potted plants from freezing windowsills, and many days the sun refuses to shine. Why not wait till spring and start these plants by seed and get them ready for planting outdoors when the summer weather will product much better results.
