Can I use DFD ?

That entirely depends on the project and your approach to complete the same.

UML always helps plan everything out for you. Depending on the size of the project and how long you'll be spending will determine if you need diagramming. As said though, it's a good practice to do even with the smallest of tasks.

As for the DFD, there is not really enough info here to explain how to go about making this diagram, sorry. Hope the first part of the reply helps though.
