独立应用程序或基于Web的mozilla或chrome附加组件

我想为Mozilla或Chrome创建独立应用程序或基于Web的插件，可以访问我所在的公告板，根据指定的搜索字段收集相关数据并将结果显示为Feed。公告牌张贴了可在浏览器中打开的通知链接。我想知道如何去做：使用的语言，平台或任何建议的阅读。任何其他帮助将不胜感激。

I want to create stand alone application or a web based add-on for Mozilla or Chrome that can access the notice board of my institute, gather relevant data based on specified search-fields and display the results as a feed. The notice board posts links of notices which can be opened in the browser. I would like to know how to go about it: the language to use , the platform or any suggested reading. Any other help will be appreciated.
