Nobody asked for a UI with more buttons. Only short cut hot keys. Anytime you have to move the mouse and click a widget it is a waste of time.
The default UI in blender was made that way for a reason. Blender has thousands of features. They try to make a lot features visible in the default UI so you can get familiar with them so you a not learning everything completely new for each stage of modeling,animating,texturing,game engine,etc.... The UI in blender is completely customizable. If you don't like something about the UI you can just take it out.
Most people try to learn on their own and fail miserably.
My best advice is to pay for some of the good tutorials on blender cookie. After all the application is free. And if you are having more problems understanding. You can probably find anything you want to find on YouTube for free.
