Firstly, "brandy" is a distilled spirit, production of which is illegal. A small batch producer could do this under the radar...now that more consumers are producing motor fuels "at home" there has been some easing of the laws.

Start by reading up on the making of wines from fruit other than grapes. Grapes provide almost all the requisite ingredients- some fruits may lack acids, sufficient or fermentable sugars etc. You will have to decide on use of sulfites or take other measures to prevent invasion of organisms besides your chosen yeast.

Making palatable wine has quite the learning curve. Turning that into brandy is a whole 'nother hill to climb.
