Coding Language in Unity3D

Known that the problem is that I don't know the coding language that I can't make a search bar so far. I decided to start learning the coding(scripting) language even though there is no time to do this.

-Choosing the default Script Editor

-Creating a new Script

-Editing a Script

-Variables

-Function Update{}

-Viewing and Editing Variables in-editor

-Attaching script to a Game Object in the Scene

-”Playing” the Game

GUI.TextField

static function TextField(position: Rect, text: string): string;

static function TextField(position: Rect, text: string, maxLength: int): string;

static function TextField(position: Rect, text: string, style: GUIStyle): string;

static function TextField(position: Rect, text: string, maxLength: int, style: GUIStyle): string;

GUI.Button

static function Button(position: Rect, text: string): bool;

static function Button(position: Rect, image: Texture): bool;

static function Button(position: Rect, content: GUIContent): bool;

static function Button(position: Rect, text: string, style: GUIStyle): bool;

static function Button(position: Rect, image: Texture, style: GUIStyle): bool;

static function Button(position: Rect, content: GUIContent, style: GUIStyle): bool;

Scripting in Unity

However, it still doesn't work for me.Knowing that it is impossible to learn and use scripting language to create a search bar in Unity3D I am sorry to admit that I cant finish the "Search Bar" task for our group in such short time.
