If you want custom template you need frontend (you do not want to go standard ERP views). But you can also create it in backend and setting correct security rules for special group of your users(e.g display only specific products).

Front end and backend are not so much different from Python view. Only you create special contollers and views more in html way.

If it is only display not edit it is not very difficult to create frontend for this.
