I managed to find an online tool
https://www.runscope.com/oauth1_tool/ that gets me past the Request Token, Authorize Token and finally Access Token of the Oauth 1.0a process. Now that I have the keys I need, I figure I just need a way to sign my request to Withings.
Or even better, is there plans to incorporate the signing process into a future Variable Convert function? Pent?
