Tree structure system with ZEND

I will need a folder/item system programmed with ZEND/dojo framework. FRONTEND Frontend there will be questions with answers. If an answer is choosen, the user comes to the next questions. Each question can be answered with yes/no or with up to 4 options. Some steps later he will get a result. So there has to be implemented a tree structure, compareable to a folder/item shop framework. It should be a simple unordered tree; each node can have 1 or more children. At the notes there should be a sortorder and should be sorted in frontend by 70%, 30%, 10%. An example: Please have a look at DATABASE at the end: Question (ID M1): Do you have a problem with your PC? If NO: END. If YES: Go to question withID M5 Question (ID M5): Problem is in the hardware | software | connection system? Option 1: "hardware" -> Go to question with ID M5 Option 2: "software" -> Go to question with ID M5 Option 3: "connection" -> Go to question with ID M5 BACKEND The database behind the system has to be managed by backend system: Add/Delete/Modify folders -> structure (children/father) -> details (name, description, image) -> sortorder Next Step will be a usermanagement / offered seperately. DATABASE behind: First we have one table: id;sort_order;header;question;yes;no;option1;option1_value;option2;option2_value;option3;option3_value;option4;option4_value;;;; M1;1;Main Questions;Do you have a problem with your PC?;M5;quit;;;;;;;;;;;; M5;2;Main Questions;Problem is in the hardware | software | connection system;;;hardware;M8;software;M21;connection;M42;;;;;; DEADLINE: 1 WEEK FOR FRONTEND 2 WEEKS FOR BACKEND I WILL AWARD THIS IF I GET A GOOD OFFER
