One could probably port the libmaple-stuff to the discovery board and upload "sketches" with the serial bootloader (or with the USB ST-link if you use Windows). It would be some work but not impossible. But I don't think anyone have done that. (And I don't think leaflabs is interested in doing it, they probably want to sell the hardware too).

So my suggestion is, if you want to get things done, buy a Maple (or two, as I did). And if you want to get into the lower level details you try that on the discovery board (or on the Maple(s), you can do that there too).

I use Maple IDE to compile for Discovery but using STM32 ST-Link Utility for firmware downloading. It not so comfortably but it works, at least in simple examples.

I added section in boards.txt with:

discovery.name=Discovery to FLASH
discovery.upload.ram.maximum_size=8000
discovery.build.f_cpu=24000000L
discovery.build.linker=maple/discovery.ld

in libmaple.h :
#define USER_ADDR_ROM 0x08000000

in maple/discovery.ld :
ram (rwx) : ORIGIN = 0x20000000, LENGTH = 8K
rom (rx) : ORIGIN = 0x08000000, LENGTH = 128K

in wirish.c :
rcc_clk_init(RCC_CLKSRC_PLL, RCC_PLLSRC_HSE, RCC_PLLMUL_3); //24 MHz
and comment out setupUSB();

in boards.h :
#define CYCLES_PER_MICROSECOND 24
#define SYSTICK_RELOAD_VAL 23999 /* takes a cycle to reload */
#define BOARD_BUTTON_PIN 2 /* PA0 USER */
#define BOARD_LED_PIN 37 /* blue led LD4 */

Also it is possible to load firmware using console util APIsample.exe from STM programming toolkit.

PS
clk_speed = (usart_num == USART1) ? 24000000UL : 12000000UL;
in usart.c
