Grab data from sites and store in spreadsheet

Basically, I need a program that goes to a website where I have to enter an application number to get the status of the application. I require a simple program that will do this, collect the relevant information I need, store it in a (spread)sheet, and keep appending to the sheet the next time it goes to fetch data. I want to be able to choose the time period between running the program automatically (Daily, Weekly, Monthly) Just need a simple program that meets the above requirements. Nothing flashy or complicated.
