DHTMLX Gantt Chart with given api functions for Get Records, Add, Update, Delete

Hi all, I need a single DHTMLX Widget, which will be a Gantt chart for projects taken from the specific APIs that will be given, populate the DHTMLX Gantt chart and make it functional with Add new records, update, delete again through the provided API. So no database is required or any special editing, only implementing as it is. The tasks will only be daily, so there won't be a single task that will be longer than 1 day. And the required columns will be the dates from the future 3 weeks, and also for the rows, will be projects and their tasks spread throughout the dates Should be pretty straight forward and require short development time, as it is only a frontend widget with few api calls.
