the farm and trade buildings are located outside of the region capital, but still in that region. just scroll around each region and you should see little farms, mines, ports, small towns, etc. if the building has a spinning gold icon over it (these are over capitals too), it means you can add something to it. just click the buliding, and then mouse over and pick one of the available options it shows on the little display. (there is usually just once choice for farm and trade buildings. there are multiple choices for towns and ports.)
if there is no spinning icon over it, then you cant currently build anything. you can still select it and see a picture of what will be available and in how many turns.
it's kinda hard to explain, but pretty easy once you figure it out.
You can also cycle through each available capital, town,farm, port, etc that you have via this cycler on the middle toolbar. use this to make sure you dont pass any over.
