We had two document libraries (say)
Document Library A
Document Library B

We need to create a folder in the above document libraries based on a data
entry form.I had a form called 'Data Entry Form-1' to add groups. so when
ever a group is added using data entry form users will select the Document
Library A or Document Library B then it should automatically create a folder
in DL-A  or DL -B. See below

Document Library A
    - Group 1
    - Group 2
    - Group 3
Document Library B
    - Group 1
    - Group 2
    - Group 3

Now there is another form called 'Data Entry Form-2' to create departments
under the groups . So users will select the document library A or B and
select the respective group in data entry form and submit. Then the system
should create a standard folder structure for that department. Within each
department folder there will be standard folder structure for see below

Document Library A
    - Group 1
          - Department 1
               - Project A
               - Project B
               - Project C
          - Department 1
               - Project A
               - Project B
               - Project C  
    - Group 2
          - Department 1
               - Project A
               - Project B
               - Project C
    - Group 3
Document Library B
    - Group 1
          - Department 1
               - Project A
               - Project B
               - Project C
    - Group 2
          - Department 1
               - Project A
               - Project B
               - Project C
    - Group 3

Can someone please help me if you had encountered the similar situation and
had a solution for this.
