Automatic searching on Google

I want a piece of software that takes a list of keywords (in a csv file), searches for each keyword in Google, and returns the number of Google results for each keywords in the csv file. For each keywords (or keyphrase), there are a number of searches to be done (with and without quotes, etcetera). I would like to hear if it is possible to have the software stand-alone and on my website, where my visitors can enter csv files and get the output on screen.
