You can't make any contributions to any IRA (traditional or Roth) unless you have compensation from working (generally wages or self-employment earnings on schedule C), plus a few odds and ends. See publication 590-a, table 1-1.

You didn't discuss the source of your income. If you or your spouse have compensation, then one or both of you can make an IRA contribution up to the usual limit ($6500 under age 50, $7500 over age 50), or up to the amount of compensation from working, whichever is less. If you don't have compensation, you can't contribute to the Roth IRA.
