The OS tells you stuff, you don't tell the OS anything. Perhaps you would like to provide more detail on the problem situation.

I already told you

The detail of your program "having" a button is essentially useless.

What are you actually trying to achieve? (NOT how you think it can be achieved)

well i'm guessing he wants to build a keyboard simulator (just a guess but look at the thread name). Which would involve the program not being able to have focus, always on top, and able to send keystrokes to the OS (I'm guessing you would have to use some private libraries to access the win32 lib and make a low level keyboard hook (which would only work for windows)... or something

You have to 'fool' the OS making it think that your program is the keyboard driver but that is far 'below' the capabilities of Java, i.e. you have to use quite a bit of JNI code (native code) to do that. Take it from me: you don't want to go there, it is far from a trivial task (if at all possible using 'simple' Java and a bit of native code). Collin (and others) already told you that.

Good; take care of the focus because you don't want the component(s) that (indirectly) caused the key event to receive that same event.
