In WinEdt you can insert text automatically with internal programmable macros.
You can do this in Kile or other frontend editor? Can be direct in file.tex via shell or bash on Ubuntu.
I need insert:
\documentclass[a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[brazil]{babel}
\usepackage{amssymb,amsfonts,indentfirst}
\usepackage[centertags]{amsmath}
\usepackage[normalem]{ulem}
\usepackage{enumerate,multicol,subfig}
\usepackage{tikz}
\usetikzlibrary{calc,positioning}
\everymath{\displaystyle}
\graphicspath{{figuras/}}
\begin{document}
\end{document}

Since you want to insert what looks like a complete document, you should use a template as described in the online documentation which provides the instructions below. Once you have a template you can select that when you start a new document.
