How to Automatically Put Related Fields into a Layout

Trying out Zoho CRM and have created a custom module to capture a specific type of customer interaction.   Want to relate that module to both a contact and account.   Added a contact lookup on the layout.   Once a contact is selected would like to automatically add the related account for that contact to the custom module.   Is there an easy way to do that?
