Before you start, make sure you've:
downloaded Unity 2.6
familiarized yourself with Unity
created menu & button graphics
noted that I script in C#
shotgunfox.net
Create a new scene
Create an empty GameObject
Add Component: GUITexture

all graphical components you are using
Edit attributes such as
<: size
<: placement
<: borders
<: image
don't edit these

To create buttons that...
... load a new scene (level)
void OnMouseUp() {
    Application.LoadLevel("Level1");
}

... more coming soon
void Method() {
    DoStuff();
}

to make advanced features like buttons that depress,
you'll need to have some skill with scripting.

To use GUIs for other interface elements...
... stay tuned
a GUI ("gooey" - Graphical User Interface) is responsible for just about every interaction between your program and your user. I'll be adding more how-to's on GUI elements soon, so check back often :)
1 GameObject for each background, button, banana,
