openoffice u3Portable db program\language?

Hi,
I'm looking for a db program\language out there that would allow me to:
1. create a db that includes forms, reports, logic, etc (like an Access db)
2. put the db and the program code into a folder
3. copy the folder to any XP+ machine
4. see, use, modify, etc. the data using only the openoffice u3program files within the folder and without having to install anything on the machine
5. have a nice pretty gui for the user

Basically I'm trying to find a totally portable (installs and runs from a single folder) db that has functionality equivalent to Access.

(I know about portableaopenoffice u3pps.com's U3 apps for OpenOffice)

Thanks...
If you write your own database, you can write almost anything you want in portable format. Once you get into automating an Access mdb file, the overhead in writing your own libraries hardly makes it worth the effort.
