Your curly brackets aren't matching. You can easily see that in the main.cpp where you have two closing ones right after each other.

Nice, I actually haven't programed in C++ since... ages )) I'm going to give it a try

Remove the curlys from: main.cpp
and add them to: mainwindow.h

Like someone said before: Compare and match the curly braces

Code:
private:

    { //REMOVE!!
    Ui::MainWindow *ui;
    // member functions
    void MainWindow::initMyWordList();
    // member variables
    static int _clickCounter;
    QStringList _wordList;
    } //REMOVE!!
Remove the curly's from above

you are missing the closing bracket. put one } before #endif

main.cpp:
Code:
#include <QtGui/QApplication>
#include "mainwindow.h"

int main(int argc, char *argv[])
{
...
}
here you got one } to much. remove the last }.

every opening bracket (curly, square, round) has to be closed again.
check your ide's or editor's settings -- almost all should have some kind of visual markers helping you to detect those trivial and easily overlocked syntactical errors.

Ok, now i get only this:

C:/Users/Edvinas/Documents/InteractiveHelloWorld/mainwindow.h:11: error: expected unqualified-id before '{' token

C:/Users/Edvinas/Documents/InteractiveHelloWorld/mainwindow.h:11: error: expected unqualified-id before '{' token

here's mainwindow.h:

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>

namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow;
{
Q_OBJECT
public:
MainWindow(QWidget *parent = 0);
~MainWindow();

public slots:
void buttonClickHandler();

protected:
void changeEvent(QEvent *e);

private:
Ui::MainWindow *ui;
// member functions
void MainWindow::initMyWordList();
// member variables
static int _clickCounter;
QStringList _wordList;

//private slots:
//void on_Button_clicked();

}
#endif // MAINWINDOW_H

class MainWindow : public QMainWindow;

remove the semicolon from the end of the line, you put a semicolon only when you finish a definition or statement, here the class definition isnt over.
Put the semi-colon at the end of the mainwindow.h after the last curly brace marking the end of the class definition.

Did that, but now I get

C:/Users/Edvinas/Documents/InteractiveHelloWorld/mainwindow.h:26: error: extra qualification 'MainWindow::' on member 'initMyWordList'

do what the error says, remove the "extra qualification 'MainWindow::' " at line 26:

void MainWindow::initMyWordList();

should be

void initMyWordList();

in your header you are declaring the class itself, no need for the namespace here.
