Does anyone have a online form generator tool like wufoo that will integrate with Wave?
I'm not aware of any direct form integrations to Wave. However, Zapier supports a number of Wave functions, and also Google Sheets.
It might be worth researching if you achieve your goal by creating a Google Form that submits into a Google Sheet, and then using Zapier to submit the data into Wave each time a new row is added to the Sheet.
Hope that helps!
