As for transferring art, Paint.Net is a great free tool but as long as your program exports to PNG's with transparent backgrounds you can then import images with transparent colors into Construct.
For solid colors, you can also copy images from MS Paint as long as the background is RGB color (255,0,255) which is a bright pink instead of white (as this is what Construct Classic uses for backgrounds).
