Cut chicken into large chunks. Combine oil, garlic, lemon juice, red pepper flakes and wine. Pour over chicken and marinate and refrigerate for 2 hours or more. Place alternating pieces of chicken, pineapple chunks, zucchini and red pepper on skewers. Whisk together ketchup, pineapple juice and olive oil. Brush entire kabob with ketchup sauce and place on grill or in broiler of oven. Cook for a total of 10-15 minutes, or until chicken is no longer pink inside and top of kabob is slightly brown. Turn the kabob frequently to cook evenly. Brush final ketchup marinate on all sides as you turn the kabob. Discard any leftover marinate.
