hi, i was wondering if any software design programs exist similar to website creators making it easy to design a website by other means than writing html code. do any programs make it easy to design software?

my goal is to design a program that can either be viewed on a website or downloaded to a computer. The program would ask the user to input some information like their height, weight, age, BMI, and some other relevant questions, and then there would be results including which vitamins and minerals they need, how many, how frequently, which foods include the nutrients and how many are included per serving. then i would like them to be able to select ingredients from the list of foods supplied and then display a list of recipes they can make with the selected ingredients, as well as a display of the nutrient totals given from the ingredients.

If anybody is interested, I would appreciate help developing the program, as I haven't made any programs before. However, any advice or references to free software to help with developing such a program would be appreciated.
