I ran into this function somewhere on the internet, I forget where, and kind of modified it use a textarea element ID

//Insert tag into text area or box
function wrapTag(text1, text2, elementID)
{
	textarea = document.getElementById(elementID);
	if (typeof(textarea.caretPos) != "undefined" && textarea.createTextRange)
	{
		var caretPos = textarea.caretPos, temp_length = caretPos.text.length;

		caretPos.text = caretPos.text.charAt(caretPos.text.length - 1) == ' ' ? text1 + caretPos.text + text2 + ' ' : text1 + caretPos.text + text2;

		if (temp_length == 0)
		{
			caretPos.moveStart("character", -text2.length);
			caretPos.moveEnd("character", -text2.length);
			caretPos.select();
		}
		else
			textarea.focus(caretPos);
	}
	// Mozilla text range wrap.
	else if (typeof(textarea.selectionStart) != "undefined")
	{
		var begin = textarea.value.substr(0, textarea.selectionStart);
		var selection = textarea.value.substr(textarea.selectionStart, textarea.selectionEnd - textarea.selectionStart);
		var end = textarea.value.substr(textarea.selectionEnd);
		var newCursorPos = textarea.selectionStart;
		var scrollPos = textarea.scrollTop;

		textarea.value = begin + text1 + selection + text2 + end;

		if (textarea.setSelectionRange)
		{
			if (selection.length == 0)
				textarea.setSelectionRange(newCursorPos + text1.length, newCursorPos + text1.length);
			else
				textarea.setSelectionRange(newCursorPos, newCursorPos + text1.length + selection.length + text2.length);
			textarea.focus();
		}
		textarea.scrollTop = scrollPos;
	}
	// Just put them on the end, then.
	else
	{
		textarea.value += text1 + text2;
		textarea.focus(textarea.value.length - 1);
	}
}

Here is a very basic functionality. My opinion, if you intend to really do anything with this you have quite a learning curve ahead of you and probably should dive in head first.
