Adwords web app

Need a web app done to build adwords campaigns. I've attached a spreadsheet with a Macro that currently builds the campaign but would like to move to this to a web app. The output of the web app will be three spreadsheets. 1) Keywords staging 2) Ad groups 3) Ads Details: A) Keywords staging spreadsheet. 1 User will enter keyword Group names (The bolded terms in column M). 2. User will enter keywords under each keyword group name. 3. User will enter keywords to go before cities (column G) 4. User will enter keywords to go after cities (column F) 5. User will enter cities The results of this page will be column A through column D B) Ad groups page: User will enter bid prices for broad, phrase, and exact and the results would be column A through C C) Ads page Column A and B will be pulled from previous page Column C will be city plus top level keyword Column D will be city plus keyword User will enter column E User will enter column F This sounds more complicated than it is, but it's a fairly simple macro as can be seen in the spreadsheet. I just need to move this to a webapp.
