1. Rinse, sort, and drain butter beans.
2. Bring butter beans, 1 tsp. salt, and 4 cups water to a boil in a saucepan over medium-high heat. Reduce heat to medium-low, and simmer, stirring occasionally, 35 minutes or until beans are tender; drain.
3. Meanwhile, combine shrimp, 1 Tbsp. oil, 1/4 tsp. pepper, and remaining 1/4 tsp. salt in a bowl, tossing to coat. Heat a grill pan over medium-high heat; cook shrimp 4 to 5 minutes or just until shrimp turn pink. Transfer to a plate, and cover loosely with aluminum foil to keep warm.
4. Heat remaining 1 Tbsp. oil in a large skillet over medium heat. Add okra; cook 3 minutes or until lightly browned. Stir in onion and next 3 ingredients; cook 3 minutes or until vegetables are tender. Add tomato and corn; sauté 3 to 4 minutes or until corn is tender. Stir in basil, butter, shrimp, and butter beans. Cook 1 minute or until butter is melted and mixture is thoroughly heated. Season with salt and pepper to taste. Serve immediately.
