RGB LED Mixer Schematic

Hi, for the past couple of months, I have been searching for a RGB LED mood light controller, but so far, all of them require a PIC(Programmable Integrated Circuit). The problem with this is that The PIC, the PIC Programmer, and the IDE for some reason wont work together(even though they are all from the same company). So recently, I thought that it would be easier to just make a color mixer, that controls each of the RGB channels individually with a potentiometer assigned to each. But, I can't find a simple one. So I made my own, but I would like to ask the Instructables community if they think it will work. Thanks ahead of time :) Here is the schematic:
