Selecting a Language for desktop application [closed]

Question

I have an idea and want to build a desktop application

Requirements: Open Source, portable, cross platform, easy to install, easy to make setup, simple GUI, high speed draft printing.

I have some options:

1. Java : easy to make jar file but don’t know how to make setup executable, swing is easy to implement
2. C#: Easy to make setup file but tools for open source are limited, difficult to implement
3. Python: Python eggs are setup file, difficult to make interface, is easy to develop, fast programmable
4. Ruby: Don’t know anything about ruby
5. C/C++ : I had used C builder and Codelite product in C and C++, it is difficult to work with crafter widgets
6. Visual Basic: Easy to build nice GUI but portability, reporting and setup issues
7. Visual Fox Pro: Microsoft open sourced version but database support is limited to sql and Microsoft Access
8. and other: Don’t know much about other languages

I want

1. An Application setup should be fast and easy to create
2. Easy to build GUI not like C++ crafter or any other external source
3. Multiple options for open source reporting tools
4. And it could run on different platforms: Linux,Windows 7/8 and others

Please, can you suggest me a language or any other resources and links that could help me to find the best solution.

I want to know how desktop applications are made from start to end in open source.

When I see setup of applications I download for various needs of requirement it doesn't speaks how it developed and what language is used for it...but its beautiful to use it..

Answer 1

Python and WxPython is used throughout the DropBox project to implement cross platform GUI. Bittorrent was also first implemented in python.

So I would advocate Python. - Easy deployment option with py2exe and py2app

If you really don't mind Qt and C++ then that would be an option as well or C++ with WxWidgets
