ANswer: Here letter G is produced using linear segments for outline method.  You may also use Bezier curves of higher degree to approximate the outline of the character. The outline will be drawn using the code given here. For filling the interior, you need to employ one of the fill area methods.   Vertices of the line segments are given as follows. 

GLint vt[][2]={{315,245}, { 315,195}, {316,190},{333,183},

{ 251,183}, {263,186}, { 270, 190},{272,195}, {272,225}, {

253, 238}, {242,236}, {235,229}, {231,219}, {227,198}, {

227,169}, { 228,152}, {233,133}, {242,124}, {248,120}, {

253,120}, {269,119}, { 273,121}, { 280,126}, {292,134}, {

299,141}, {305,149}, {312,162}, {312,111}, {307,110}, {307,

120}, {304, 130}, {301, 133}, {298, 131}, { 289, 125},

{279, 120}, {266, 113}, {251, 109}, {239, 110},{229,110},

{219,114}, {208,120}, {196,129}, {190,138}, {185,148},

{181, 158}, {180,172},{180,184}, {180,196}, {184, 203},

{189, 214}, {198, 226}, {211, 235}, {220,242}, {230,245},

{245,247}, {260, 247}, {271, 241}, {284, 236}, {293, 231},

{299, 231}, {306, 235}, {315,245}}; 

The code uses simple line loop to produce the character.   

void lineG(void)

{glBegin(GL_LINE_LOOP);

for(int i = 0;i<62;i++) {

 vt[i][1]=480-vt[i][1];

 glVertex2iv(vt[i]);}

 glEnd();

}  

Call the function lineG in your display function. Similar is the code for letter ' t'.
