Ok. You know what you have.
What you don't have is a question. Nobody here knows why you posted this since you haven't asked anything. What is it you are looking for?
I recommend you read the FAQ about How to ask a good question so the volunteers will be able to help you.

Well I have no idea what you're having problems with because you haven't asked a question (you've just stated what needs to be done).

To accomplish what you want, add a panel to the page/window/form (whatever you call it) and set it's Visible property to False. Then when the user clicks the button set it's Visible property to True....

It's really that simple.

If i understand you correctly use the VISIBLE="FALSE" property of the panel and when you click the button set it to true on your click event.
