New screen for custom table

To start, I am very new to the Acumatica environment.. 

We have a customer that has a hosted Acumatica setup and needs a custom table (and its data) imported into the system.. So the scenario is that we need a customization project that will 

1. Create the table (if doesn’t already exist in database)
2. Create the screen with all of the data fields form the table
3. Have simple CRUD functionality

I am able to use the database script component of the customization project to create the table but I am having a tough time linking the new screen to the table/correct data fields. Then I am having a tough time with the simple CRUD functions in the graph. 

I am mostly looking for some examples or more thorough documentation on topics like this so I can dive in and learn how to do this the correct way.

Thanks in advance for any help
