You need the asterisk. The fact that it is an outlet or not has nothing
to do with the fact that in Objective-C you cannot statically allocate
objects

NSButton myButton // wrong
NSButton* myButton // right

Yes, outlets are pointer but you need to declare a pointer in your
header (NSButton myButton is not defining a pointer to a button,
NSButton* myButton is)

Look at the examples in the /Developer/Examples/InterfaceBuilder and
/Developer/Examples/Cocoa
