Automating Google

Hello StackOverFlow members, this is a general knowledge based question regarding Google.

My goal : To automate a web page such as Google. The over-all objective is to create a web browser that automates a Google search with button click event. 1. Navigate to Google.com 2. Click search bar 3. Enter text ("Define Hello" for example) 4. Click search

I have seen add-ons such as selenium for Firefox, this is a primary example of what I wish to achieve, however I want my application to be stand-alone meaning fully source/not using a separate internet browser like Firefox, but rather using my internet browser project that I have built.

So my question is, what do I need to look at for achieving this?

I have background in C# and the web browser is built, but when using google for searches like "Web browser automation" I do not find what I am looking for, there's no relevant source for this to my knowledge.

Any kind of guidance would be greatly appreciated, is this an application that would be built using Java, would I need a server?

Thanks for any help you experienced programmers can give, if you have any relevant questions I'll be sure to update this op with the answer as soon as possible.
