To write the least code, use SmartGWT Pro. It provides a wizard that allows you to just pick from a list of Hibernate entities you've created, and instantly you have the ability to perform all CRUD operations on that entity, no code required. Then you can add business logic.

The link about is just screenshots, but there are several Hibernate samples in the showcase. See especially the Master-Detail Batch Load and Save sample.

As far as performance, real-world performance of most enterprise apps is dictated by how often the application has to contact the server. In this area SmartGWT has a large lead because of features like Adaptive Filtering (see the Featured area in the SmartGWT showcase).

Almost all reports we receive of SmartGWT being "slow" are due to having Firebug enabled. Disable Firebug and performance is fine, so normal end users will never perceive slowness.
