I have 10 or 30 or even 43242432 variables that can be set to 1 or 0

I want, when the player presses some key, to a panel to appear, with some choices, in this case are the things to appear in the radar.

I have to set the variables to 0 or 1, right. But now there's a problem..

How can i create a panel that, detects the choice the player clicks with the cursor and then activates/deactivates the variable according to the choice?

I never used panels..
