Bridge script UI folder path

I am using a custom Bridge script to load stacks into photoshop layers.

Every time I run the script I have to change the folder path manually to save the images in a new folder.

I would like to find out if a UI dialog can be used with the script to edit the folder path.

The UI dialog would offer to use the previous folder path or to enter/select a new folder location.

I have not been able to incorporate the core Javascript class Folder successfully with the Bridge script.

The scripts hangs, does not complete when I add the core JS Folder class.

How do I approach building a script UI in Bridge?

Are there any simple Bridge script UI samples available to deconstruct?
