Is it possible to have a captcha protection on forms made on a non-custom solution?

It's not possible out of the box. However you can achieve this by creating a custom FormSaveProvider (http://engage.dynamicweb.dk/Admin/Public/Download.aspx?File=Files%2fFiler%2fDocumentation%2fDevelopment%2fModules%2f(en-US)+Data+Management+Extensibility+API.pdf). You would have to do some coding to make this work.

The overall idea is to have a custom FormSaveProvider that validates the CAPTCHA. If it validates successfully then no further action is required. If it fails, however, then delete the form data from the database.
The reason for this backward way of doing it is because the DefaultSaveProvider (the one that saves the data to the DB) is always run as the first one to ensure no loss of data.
