Hey volocom7!
Thanks for reaching out to us!
Yes you definitely can. First though if you created the button using the Avia Layout Builder, you need to enable debugging http://kriesi.at/documentation/enfold/enable-advanced-layout-builder-debug/
Now that debugging is enabled you can find the shortcode for the button and place that in the text widget.
Let me know if you need further assistance.
Regards,
Jordan
