Hey,
I know the app area can be frustrating...
If you haven't, go take a look at my old application, its in the Freelancer area. Took me about 3 months to make it. I think there are 7 pages in that app.
It gets hard, you feel like you hit that brick wall. But don't give in. Every image you make is getting better. Google tutorials, watch YouTube videos of basic tag making. Just play around with your program. You can do it.
