Enable/Disable button question

Hey there,

My UI is really straight forward. It has an"OK" button, a "cancel" button and a "disable" button.

Basically, what I want to do is, when I click the "disable" button, it disables the ok and cancel buttons.

Once the disable button is clicked, and the other buttons are disabled, the disable button should then turn to an enable button, which will re-enable the buttons.

Here is what I have so far. The buttons there, but they all just say "clicked" when clicked on. I'm not sure how to disable the buttons and etc.

Please forgive me in advance, I'm super new to this. Be easy on me please!
