You haven't said how much you know about databases. Presumably you can make a table with the information.
Basically:
Create a form called "PartLookup"
Add a text box called "PartNumber" to the form.
Create a query based on the table and add the fields you want to see.
Set the PartNumber column Where: Forms!PartLookup.PartNumber
Add a Subform to the form.
Follow the wizard and select the query as its DataSource.
Set the Subform Default View property to Form.
Add the PartLookup form to the Switchboard.
Hope this helps.
