first of all, take a deep breath kingyo, and slow down. wb's are not easy to make! and you have to take your time to understand each component.
Listen to Vstyler, cause he knows what hes talking about. hes a master. Why dont you download a few skins and open them up and have a look at the button images different people have used on their wb's. I mean actaully open up the skin in an art progam and look at the size, numbers of buttons in one frame ect, and notice the states, where they are situated ect.
Sometimes disecting someone elses skin is the way to go

Once you have worked it out, you will be laughing........ and yes we are here to help also when you get stuck
normal uis buttons are pretty simple, its the perpixel ones that are a pretty different.
