Pages comes with 16 built in templates.
You can't really create your own, but the workaround is easy and does the job. If you create a pages document and export it to iTunes, iDisk, or webDAV (can be made to work with DropBox), you can reimport as many copies as you want.
While the webDAV(DropBox) and iDisk solutions require you to have an internet connection, when you export to iTunes it stays on you iPad unless you go to iTunes on the computer and remove it.
If all you are looking for is a questionnaire or poll type applications you should search for them in the App Store. I believe there are several that may work better for you than cobbling something together in Pages.
If you don't like any of them I recommend Numbers as a better way to set up a check/mark or choose the answer type questionnaire. Pages will work better if you need to type more flexible answers.
