An IBM iSeries user recently wrote the editors of Search400.com asking about the best programming language for developing GUI applications.
Currently they run only RPG-based green-screen programs on their iSeries, but they are looking to move into the GUI realm. For now, it will be limited to new applications. All of their users connect via a LAN, most using a Windows Terminal Server desktop.
In addition to RPG, they also have some Visual Basic and limited Java experience. What, in your opinion, would be the best language for them to use and why?
