There are a lot of Nxt users who can't launch "official" Nxt client. I tend to agree that installing Java and running Jetty sucessfully is too complicated for ordinary users. When advanced features come the situation could become worse, coz businessmen r not so tech-savvy as most of us.

U could help Nxt community by developing a "gateway" to Nxt decentralized exchange. This gateway is just a software that talks to Nxt node and visualizes data. It's not necessary to implement mining, transaction handling and other base features. Ur soft is supposed to send simple HTTP requests like "list assets", "place order". The only requirement is that it should be user-friendly (easy to install/run and easy to use).

Post here if u would like to develop such software. Provide a short description what platform ur soft will be for and how it will look like, please.

U'll get documentation and access to a server that hosts Nxt node with enabled exchange. We can't provide *.class files coz they can be easily disassembled.
