Not really.
However, if you just want a program to convert ppm to usable files, you don't really need anything more than netpbm, like this:
Download the "binaries" zip from the netpbm download page Extract all the files, browse to the bin folder and, hold shift and right click when inside the folder, select "Open command prompt here" and run the following command

ppmtobmp C:\"Path to Powder Toy"\file.ppm > C:\"Output path"\file.bmp
