Widget Button

Hello all,
I have an android game where i have a whole heap of buttons for spells on the very left hand side on my screen. The game is also touch and move so when a player presses on the screen the character will go there the issue i have is when i press on a spells the character will walk in that direction is there anything i can put behind the buttons to make it a dead zone so the player wont respond to that part of the screen cheers
