Hello! I try to use emWIN on my lpc1788 board with ATM0430d5-T LCD TFT display and SAMSUNG K4S561632J SDRAM. There is no available drivers for my board and LCD. So I am going to make it by myself. Is it enough to make following function:

LCD_X_DisplayDriver();
with commands
LCD_X_INITCONTROLLER
LCD_X_SETVRAMADDR_INFO
LCD_X_ON
LCD_X_OFF
LCD_X_SETLUTENTRY
LCD_X_SETORG

LCD_X_InitController()

LCD_GetBitsPerPixel()
LCD_GetBitsPerPixelEx()
LCD_GetNumColors()
LCD_GetNumColorsEx()
LCD_GetVXSize()
LCD_GetVXSizeEx()
LCD_GetVYSize()
LCD_GetVYSizeEx()
LCD_GetXMag()
LCD_GetXSize()
LCD_GetXSizeEx()
LCD_GetYMag()
CD_GetYSize()
LCD_GetYSizeEx()

LCD_SetDevFunc()
LCD_SetSizeEx()
LCD_SetVRAMAddrEx()
LCD_SetVSizeEx()

LCD_ControlCache()
?

Should I do something else?

A sample project LCD\Lcd_GFT035A320240Y from code.bundle.lpc17xx.keil_ works on my board. It didn't configured for my resolution, but it works. Does it mean that free lcd drivers for emWIN suit me? What should I do to make emWIN work on my board if they do?

I suggest you start with the emWin example for the LPC1788 and EA QVGA here: http://www.lpcware.com/content/project/emwin-graphics-library

Then replace the LCD and SDRAM driver code in LCDConf.c with the code from the Keil sample project that works for your hardware. It will be obvious which of the functions you list need to be implemented to get it going on a different LCD.
