Software alternative
Paint.NET - http://www.getpaint.net/index.html
Paint.NET is a free software that has very similar tools and layout to Photoshop. There aren't as many filters or brush strokes but the software is very easy to use as a beginner. If you were thinking about investing in Photoshop I would strongly advise you to check this out first as it might be what you're looking for and you wont have to spend lots of money on an expensive software
