The question isn't clear, but in a WinForm you can call 

this.Close()

on the Click event of your Close button.
Every object or variable used by the form will be destroyed. Be careful! running background threads will still be alive until they terminate.

About saving the status of your variables it completely depends on what you need to with them after; you can either keep them in memory and pass them around like parameters or write on a disk (maybe with serialization?).
We need to know more.

You may want to take a look at Application Configuration ( http://msdn.microsoft.com/en-us/library/ms184658(VS.80).aspx ).

With both of your buttons, inside the "onclick" event, call a function that will save the content of the form. You also need this call in the "onclose" event of the form, in case the user presses the top-right X button (or not, if you dont want data to be saved at that moment)

Inside that function, you will need some code that will save data to the registry.

Writing in the registry is easy. This webpage also explain how to get the data back. The values you will write will be the textbox.Value and such
