Hi, I started with C++ development recently, and I think I'm ready to start building GUIs for my apps.
I'm thinking about using Qt, since it is the most popular C++ GUI library, but the licensing is really confusing, and there isn't a lawyer nearby that understands software licensing who can explain this to me.
I will only use Qt (as it is) for the GUI, and won't change anything inside the library. So I'm basically just going to link parts of my app with Qt and won't mind if I must release my GUI as open source, but if I can keep it closed source, it will be better. I'm not going to be distributing apps immediately, but I'm planning to by the end of the year.
Do I need to purchase a commercial license, or can I just use it under LGPL?
