attach UI to script

I stated this post in ht photoshop forum originally.

I use a custom script to batch process files into photoshop layers.

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

Can a UI dialog be implemented into a script used for batch file processing?

The UI dialog:

Enter folder path

Remember the last folder path used

When the scripts runs the UI dialog displays. After the user enters the folder path the the scripts batch processes a folder of images.
