Also you might want to look at PabloDraw, it is windows based and is very easy and powerful to use, for an example look at the welcome screen on my gameserver, it was made with PabloDraw. But in the end it is what you need the program to do, each has their own strengths.
If you think PabloDraw is for you, here is a link to their site.
