Website Widget w/ mySQL backend

We need help developing a widget that we can plug into our existing PHP/mySQL website. The widget will be approx 200 x 600 pixels. It will be an input form than lists a number of food ingredients. User must be able to input quantities next to the food ingredients they plan to eat, some personal information, and then they hit the "calculate" button. Back End Database tables include: Table ONE: "Ingredients" (ingredient_id, ingredient_name, ingredient_thumb, ingredient_image, active) Table TWO: "nutrients" (nutrient_id, nutrient_name, active) Table THREE: "unit_of_measure" (unit_of_measure_id, unit_of_measure_name, active) Table FOUR: "ingredient_nutrients" (ingredient_id, nutrient_id, unit_of_measure_id, value) Table FIVE: "user_types" (user_type_id, user_type_description, user_type_gender, user_type_age_min, user_type_age_max, active) Table SIX: "min_daily_requirements" (user_type_id, nutrient_id, unit_of_measure_id, value) Table SEVEN: "users" (user_id, user_type_id, user_name, user_email) Table EIGHT: "recipes" (recipe_id, user_id) Table NINE: "recipe_ingredients (recipe_id, ingredient_id, unit_of_measure_id, value) Process looks like: 1. widget displays ingredients and thumbnail images 2. user enters quantity next to each ingredient 3. user enters their name and email 4. user selects gender and enters age 5. user hits "calculate" button 6. widget refreshes and displays the nutritional content of the recipe as well as % of daily nutritional allowance We can help provide more details, table contents, etc. to the winner.
