Ahoj, takhle ti nikdo moc neporadí. Hoď sem nějaké kódy...
Také by bylo fajn se s námi podělit, jaké technologie používáš... Swing/JavaFX?

Ve swingu nedělám - je to přežitek, ale tady by jsi mohl
najít odpověď.
Jinak, než se pustíš do něčeho většího, měl by jsi si alespoň projít
zdejší tutorialy...
