brake pad change went bad

[FZR_600_90]

I was due for new pad so i proceed to remove them on one side, the inside piston were stuck causing the pad to be used uneven (inside was almost to the metal and outside has lots of meat left) so i sprayed some wd40 around the inside piston to Free them up and pushed them back in...while i did that the outside piston popped out and major oil leak did follow...what should i do now ?

Put the piston back in. Add brake fluid, bleed brakes.
