Question: I am developing an App where I would need to perform HTTP Request using C#.
Had in been PHP, I could use the HttpRequest class. Which class or group of class is best matched for the PHP HttpRequest by which I could make GET and POST Request.

Answer: 
You can use [QTextEdit](http://doc.qt.nokia.com/4.6/qtextedit.html) and [QSyntaxHighlighter](http://doc.qt.nokia.com/4.6/qsyntaxhighlighter.html) together to get text editing features with syntax highlighting. See Qt's richtext\syntaxhighlighter example.

QtScript is based on the ECMAScript scripting language as is JavaScript, so I guess you could use JavaScript syntax highlighting without any big problems. So if you don't want to code the new QSyntaxHighlighter from scratch, maybe you could use this [JavaScript editing widget](http://ariya.blogspot.com/2010/09/minimalistic-javascript-editing-widget.html).
* Full-fledged code editor widget: [QCodeEdit](http://qcodeedit.org/)
* Very simple solution: [QtScript highlighter](http://www.qtcentre.org/threads/25501-QtScript-script-text-editor-for-Qt-4-4-3-with-Syntax-Highlighter) (MultiLineCommentHighlighter class is defined [here](http://www.qtcentre.org/archive/index.php/t-25483.html))
