I would like to make a simple scheme looking like tree diagram (structure like this or that). The problem is that all the packages I did try, could make nice binary trees with little information in the nodes. My tree is not binary and I need to put some words on each node, so what tools could you recommend me to try for this?

tikz-qtree is an awesome package for more convenient tree drawing in tikz.
Here is a brief tutorial to get you started: As in any other piece of software, break it down into its components.
First step is to draw the nodes and give them name. Lets start with the top node located at the origin and name it
(top):\documentclass{article} \usepackage{tikz} \begin{document} \begin{tikzpicture} \node (top) at (0,0) {$\{x,y\}$}; \end{tikzpicture} \end{document}So now you have:
which is not too exciting.
Note: I included the full code here, but subsequent steps I show only the additions to the above to make it easier to follow.
Next, add the left and right nodes. These should be located relative to the
(top)node so that in case we decide to move the position of the top node, these two will move along with it:\node [below left of=top] (left) {$x$}; \node [below right of=top] (right) {$y$};So, now things a looking a bit more useful:
If these are not far enough apart, you could move them, again relatively, by using something like
xshift=<length>, orxshift=<length>.Next step is to draw the lines connecting these nodes via their node names (color used here to see the correspondence between the code and the output):
\draw [red, thick] (top) -- (left); \draw [blue, thick] (top) -- (right);to get:
If the lines are not long enough you can shorten then via a negative amount. For the top we use
shorten <=-2pt, and for the bottomshorten >=-2ptto get:
Using the
tosyntax as opposed to the--allows you to get fancier and control the angle at the out point viaout=<angle>, and the angle of the line coming in viain=<angle>:\draw [red, thick, shorten <=-2pt, shorten >=-2pt, out=-120, in=90] (top) to (left); \draw [blue, thick, shorten <=-2pt, shorten >=-2pt, out=-60, in=90] (top) to (right);which if it had been used below would have produced:
As pointed out by Paul Gaborit, the
outandinoptions are really only for thetodirective so some might prefer a syntax that more explicitly places those options for thetoas in:\draw [red, thick, shorten <=-2pt, shorten >=-2pt] (top) to [out=-120, in=90] (left); \draw [blue, thick, shorten <=-2pt, shorten >=-2pt] (top) to [out=-60, in=90] (right);

Other tutorial like answers here which might be useful for new tikz users include:
Code:
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
% First, locate each of the nodes and name them
\node (top) at (0,0) {$\{x,y\}$};
\node [below left of=top] (left) {$x$};
\node [below right of=top] (right) {$y$};
% Now draw the lines:
\draw [red, thick, shorten <=-2pt, shorten >=-2pt] (top) -- (left);
\draw [blue, thick, shorten <=-2pt, shorten >=-2pt] (top) -- (right);
\end{tikzpicture}
\end{document}

I think TikZ can do that without problem and without library. It's possible to add some parameters if you want to change something automatically. You can with the next method to scale without problem.
If you want to modify the position with parameters:
