using vanilla dhtmlx scheduler with java planner (license)

Hi,
i am planning to use dhtmlx scheduler with javaplanner, i know why not use the javaplanner, well i want to get more control on the scheduler, like integrating mini calendar out of the scheduler and also i want to use dhtmlx layout, at the same time i want to use the hibernate capabilities of planner.

  1. my question, do you think i don’t need to use dhmtlx vanilla version and still can get full control on the presentation layout arrangement of java planner.

  2. what license(s) i need to buy after i am done with the proof of concept and decide to go ahead with above mentioned solution.

do i need to buy both dhtmlx suite license or just java planner,

if just java planner can i use dhtmlx suite components like windows, forms etc.

Thanks
