The restrictions would apply only to distribution of the solution. However, there is nothing that would prevent you from doing it strictly for your own purposes or use. Nothing in either license would prohibit you doing it for yourself. Unfortunately, the GPL's lack of freedom would prevent you from helping others by making your solution available to the public. -- Best regards, William
