Today I came to know about the open source software called wxPython . This has basic core libraries for the Windows, MAC, Linux. The user has to write the UI/code in python using these wxPython APIs. These APIs will be common across all platforms. You can easily port this code into other platforms. URL for wxPython: wxPython I am a novice for this.. Some time in future I might use this to create some cross platform apps... There is one more library called tkInter . This also looks cool. There is a python IDE which looks super cool with the black theme i like so much. its called pyCharm
