This screenshot displays the initial screen you'll see in-game - and your main overview screen. It will show your income, currently stored resources, and the time it will take to fill your Store Houses on the left hand side. On the right you'll see your settlement and any buildings you have developed - mouseover and click within your settlement to build additional structures.
Any buildings currently in construction will also appear in the left menu. Note that if you cancel a building, you will only receive 90% of the resources you initially invested in it.
The top menu has a number of useful options - "Castle" is the screen shown in the screenshot, "World" is a map of the world, further described here, "Army" allows you to build and manage your battle units, and "Hero" allows you to assign skills to your hero.
